What is high grade silica sand used for?

Silica sand is a new type of hard, wear-resistant and stable composite stone with silica as the main component, also called silica, mostly presented as transparent or translucent colourless, with a hardness level of 7 and a relative density of 2.65, with high refractory properties. Silica sand is formed after crushing and sand making, and is a very important industrial raw material.

Due to its chemical stability, good piezoelectricity, high melting point and hardness, High quality silica sand is widely used in glass, chemicals, casting, metallurgy and ceramics after processing.

How is silica sand processed? What kinds of equipment are needed?

METHOD 1: Dry Silica Sand Beneficiation Technology

Raw silica ore is coarsely crushed by jaw crusher → sorted by AMD large ore particle optical sorter → medium and fine crushing by cone crusher → screening by vibrating screen - sorted by AMD dry ore particle optical sorter → sand making by impact sand making machine → acid washing → drying → magnetic separation → sorted by AMD ore powder optical sorter → high purity silica sand is obtained.

METHOD 2: Wet Silica Sand Beneficiation Technology

The wet quartz powder manufacturing process is similar to the dry quartz powder manufacturing process, mainly with restrictions on water source and water quantity requirements, suitable for use in working conditions where environmental requirements are very strict and sufficient water sources are available. The processing flow is as follows.

Raw quartzite is coarsely crushed by jaw crusher → sorted by AMD large ore particle optical sorter → medium and fine crushing by cone crusher → screening-cleaning by vibrating screen → sorted by AMD wet ore particle sorter → sand making by impact sand making machine → acid washing → drying → magnetic separation → sorted by AMD ore powder sorter → get high purity quartz sand.

A lithium-ion battery is primarily composed of a cathode, anode, electrolyte, and separator. During charging, lithium ions de-intercalate from the cathode material, migrate through the electrolyte, and intercalate into the anode material. During discharging, lithium ions move in the reverse direction, de-intercalating from the anode and returning to the cathode through the electrolyte. This repeated intercalation and de-intercalation of lithium ions between the cathode and anode enables the battery’s charge-discharge function, providing electrical energy to devices.

Capacity degradation in lithium-ion batteries is categorized into reversible capacity loss and irreversible capacity loss. Reversible capacity loss is relatively "mild" and can be partially recovered by adjusting charge-discharge protocols (e.g., optimizing charging current, voltage limits) and improving usage conditions (e.g., temperature/humidity control). In contrast, irreversible capacity loss arises from irreversible changes within the battery, leading to permanent capacity reduction. According to GB/T 31484-2015 standards for cycle life testing: "During standard cycle life testing, the discharge capacity shall not fall below 90% of the initial capacity after 500 cycles, or 80% after 1,000 cycles." If the battery exhibits rapid capacity decline within these standard cycle ranges, it is classified as capacity fade failure, typically involving irreversible degradation mechanisms.

I. Material-Related Factors

1. Cathode Material Structural Degradation

2. Excessive SEI Growth on Anode Surfaces

3. Electrolyte Decomposition and Degradation

4. Current Collector Corrosion

5. Trace Impurities in the Battery System

Transition metal impurities (Fe, Ni, Co) introduced via raw materials may participate in redox reactions, catalyze electrolyte decomposition, or compete with Li⁺ intercalation. These impurities also destabilize SEI layers, exacerbating anode side reactions.

II. Operational Environmental Factors

1. Temperature Effects

2. Charge-Discharge Rates (C-Rates)

3. Overcharge/Over-Discharge

• Over-discharge over-lithiates anodes, destabilizing their structure and inducing electrolyte reduction. Early smartphones without protection circuits showed rapid capacity loss under such abuse.

Consequences of Battery Failure

Severe capacity degradation manifests as insufficient runtime (e.g., short device operation after charging) or abnormal charging behavior (e.g., slow charging). In critical applications:

• Grid-scale energy storage: Failed batteries destabilize power supply reliability, threatening grid security.

Lithium plating refers to the detrimental phenomenon where lithium ions fail to intercalate into the graphite anode during charging processes, instead undergoing electrochemical reduction to form metallic lithium deposits. This results in the formation of characteristic silver-gray lithium metal layers or dendritic lithium crystals on the anode surface.

Conventionally, battery disassembly has been the primary method for confirming suspected lithium plating incidents, particularly when observable capacity anomalies or visible dendritic growth are present. However, advanced non-destructive diagnostic techniques now enable accurate detection through sophisticated electrochemical analysis.

Ⅰ. Advanced Non-Destructive Detection Methodologies:

1. Voltage Profile Deconvolution Analysis

During constant-current (CC) charging cycles, lithium-ion batteries typically exhibit a monotonically increasing voltage curve proportional to state-of-charge (SOC). The emergence of premature voltage plateau depression during the constant-voltage (CV) charging phase serves as a critical indicator of lithium plating. This phenomenon occurs due to the irreversible consumption of active lithium inventory through plating reactions, resulting in diminished reversible capacity and accelerated voltage decline.

2. Differential Capacity Analysis (dV/dQ)

This analytical technique involves calculating the first derivative of voltage with respect to capacity (dV/dQ) to identify characteristic phase transition peaks in graphite anodes. Lithium plating manifests through distinct alterations in these phase transition signatures, including:

• Peak position displacement (>20mV shift indicates severe intercalation obstruction)

• Peak intensity attenuation (reduced magnitude suggests compromised lithium insertion kinetics)

• Peak shape distortion (asymmetric broadening reflects heterogeneous reaction distribution)

3. Electrochemical Impedance Spectroscopy (EIS) Diagnostics

Lithium plating induces significant changes in interfacial charge transfer dynamics:

• Formation of electrically isolated "dead lithium" deposits increases ionic transport resistance

• SEI (Solid Electrolyte Interphase) layer reconstruction alters charge transfer impedance (Rct)

• High-frequency semicircle expansion in Nyquist plots (typically 100Hz-10kHz range) correlates with interfacial impedance growth

• Mid-frequency semicircle deformation reflects lithium deposition-induced charge transfer limitations

4. Ultrasonic Time-of-Flight (TOF) Characterization

This spatially resolved acoustic technique capitalizes on lithium-ion batteries' stratified architecture:

• Baseline TOF calibration establishes reference acoustic signatures

• Lithium deposition creates acoustic impedance discontinuities (ΔZ > 15% indicates significant plating)

• Echo waveform analysis detects:

- Signal amplitude attenuation (5-15dB variation)

- Phase shift anomalies (>5° deviation)

- Time-domain reflection coefficient changes (>8% threshold)

Current technical limitations:

• Primarily applicable to pouch cell configurations (aluminum casing in prismatic cells causes 90%+ ultrasonic attenuation)

• Detection threshold requires minimum 2.8% volume fraction of metallic lithium

• Requires sophisticated signal processing algorithms (e.g., wavelet transform denoising)

Ⅱ. Supplementary Detection Indicators:

• Coulombic efficiency depression (ΔCE > 0.5% per cycle)

• Open-circuit voltage (OCV) relaxation abnormalities

• Differential voltage analysis (dQ/dV) hysteresis expansion

• Thermal signature anomalies during relaxation phases

Ⅲ. Implementation Protocols:

• Establish baseline parameters through initial formation cycles

• Implement multi-modal detection protocol integration

• Apply machine learning algorithms for pattern recognition

• Perform cross-validation with reference electrode measurements

This comprehensive approach enables early-stage lithium plating detection with >92% accuracy while maintaining battery integrity, significantly enhancing safety protocols in battery management systems (BMS).

Gold in nature exists mostly in the form of monomers, and metal compounds such as selenium, tellurium, and antimony are occasionally seen, but non-metallic compounds are extremely rare. Gold ores are mainly divided into two categories: alluvial gold ores and rock gold ores, while rock gold ores can be subdivided into quartz vein type, fracture zone alteration rock type, fine vein dipping type, and quartz-calcite type. To address the characteristics and pain points of different types of gold ores, HT color sorter's ore sorting and AI sorting technology provide customized solutions to promote the upgrading of the beneficiation process to high efficiency and green.

First, alluvial gold mine: water conservation and efficiency, cracking the problem of resource recovery Alluvial gold ore is formed by primary gold ore through long-term water erosion, wind erosion and deposition, and according to the cause can be divided into gravity sand, flowing water sand, glacial sand and coastal (lake) sand. The beneficiation of alluvial gold is mainly re-election and enrichment. Most of the alluvial gold sands in China are flaky, or because of the long history of sand mining, the rest are flaky fine particles. Easily selectable alluvial gold ores should have more sand and less mud, with coarse sand and fine gold, otherwise they are considered difficult to select. In China, water guns and sand mining boats are commonly used for sand mining. Boundary grades are usually not required due to low cost and large scale. Generally industrial grade up to 0.1g/t (0.15g/m³) can be mined, while 0.3g/t alluvial gold ore is already rich. Alluvial gold mining cannot be done without water, and whether water can be recovered or not is the main factor affecting the cost of alluvial gold mining.

Second, rock gold mine: classification policy, overcome the bottleneck of mineral processing technology From the geological reasons, rock gold can be roughly divided into three categories: igneous rock, sedimentary rock and metamorphic rock. Among them, China is dominated by igneous and metamorphic rocks, and there are fewer gold deposits in sedimentary rocks. According to the data from previous exploration, the grade of gold in igneous rocks decreases with the acidity of the rocks. The highest grade is pure peridotite and olivine, followed by amphibolite, and basalt. The lowest grade is in granite. However, it is well known that the higher the basic properties of a rock, the more susceptible it is to oxidation and weathering. Therefore, it is often said that “easy to grind and difficult to select, easy to select and difficult to grind” is a certain truth. Generally speaking, rock gold ore can be divided into quartz vein type, broken zone alteration rock type, fine vein dipping type, quartz calcite type from the point of view of mineral processing.

1. Quartz vein type gold ore: digging gold from waste rock, realize double benefits quartz vein type gold ore with pyrite as the main gold-carrying minerals, gold endowed with vein fissures. Traditional flotation needs to process a large amount of quartz vein, resulting in high cost and waste of resources.  Ore color sorter using pure quartz and pyrite associated quartz ore surface characteristics of the industry, the use of photoelectric color sorter technology to sort out the pure quartz and gold-bearing pyrite, selected pure quartz ore can be directly sold as raw materials; and gold-bearing pyrite concentrate grade can be greatly improved, to a place in Henan, for example, the vein quartz gold ore, into the flotation of the amount of ore is reduced by 40%, the grade of the gold ore is increased by morhttps://www.htcolorsorter.com/e than 50%.

2. Crushing zone alteration rock type gold mine: pre-enrichment to reduce the risk of tailings Crushing zone alteration gold deposit veins are mainly quartz and silk mica, metal minerals are mainly pyrite, in the form of fine vein dipping, gold and sulfide ores are coexisting, and the peripheral rock alteration is dominated by silica, kaolinite, silk mica and carbonate. In addition to pyrite, the sulfide ore is readily associated with chalcopyrite, galena, sphalerite, etc. Deposits of this type are usually easy to select and high recoveries can be obtained by individual flotation. If the weathering is serious, the tailings can be recovered twice by whole mud cyanidation. As for the low-grade ores in this type of mines, the gold-bearing sulfide ores in the associated ores are identified through the use of AI ore sorting, and the low-grade enclosing rocks are thrown away, so as to achieve the upgrading of the gold grade to realize the recycling of the gold ore resources. 

3. Quartz-calcite-type gold ore: efficient activation of dispersed resources The vein minerals of quartz-calcite gold deposits are quartz and calcite, and the gold minerals are bubbling in the vein minerals and metal minerals, and the metal minerals range from simple to complex, and the majority of them contain poisonous sands, staghornite, magnetic pyrite, black copper ore and so on. Due to the good distribution of gold and the large influence of metal minerals on the mineral selection process, it is difficult to take into account both the efficiency and economy of the sorting process through a single process. efficiency and economy.   Pre-selection is carried out by capturing the differences in multi-dimensional characteristics of quartz, calcite and associated minerals on the surface (such as spots, color, texture, etc.), and the pre-selected concentrate is used for recovering gold through flotation, which can greatly reduce the amount of flotation scale.

Technology empowerment: from cost reduction and efficiency increase to green mine The core of HT color sorter sorting technology lies in multi-dimensional perception and resource recycling: accurate sorting: spectral recognition accuracy > 99%, can handle low-grade ore with a boundary grade of 0.3g/t; zero-waste target: quartz, calcite and other veins are turned into treasures, and the amount of tailings is reduced by 50%-70%.  HT color sorter technology not only solves the problem of “high cost and low recovery rate” in traditional ore dressing, but also reconstructs the economic model of mines with resourceful thinking by precisely adapting to different types of rock gold deposits. From “turning waste rock into building materials” for quartz vein mines to “AI pre-enrichment” for complex associated mines, technological innovation is driving the industry to move forward in the direction of high efficiency, greenness and sustainability.

In the operation of hotels, energy costs are a significant factor that cannot be overlooked. The advent of heat recovery chillers offers an efficient and energy-saving solution for hotels.

A heat recovery chiller, in simple terms, not only performs cooling tasks but also effectively recovers heat. For hotels, this is a highly practical feature. Traditional chillers only accomplish cooling, wasting the heat generated. However, heat recovery chillers are different; they can convert the otherwise wasted heat into usable hot water.

In principle, during the cooling cycle of a chiller, the refrigerant releases heat. Heat recovery chillers use special devices to collect this heat, and through a series of heat exchange processes, they can produce hot water. This hot water can be used in various scenarios within the hotel. For example, it can supply water for guest rooms' washing and brushing, provide hot water for the hotel's restaurant kitchen, and even be used for heating the swimming pool.

From a cost perspective, using a heat recovery chiller in a hotel means getting hot water for free while cooling. This significantly reduces the energy consumption required for the hotel to prepare hot water separately, such as reducing the use of gas or electric water heaters. Over time, this can save the hotel a considerable amount of money.

From an environmental perspective, the use of this equipment also reduces energy waste and lowers the hotel's carbon emissions. This aligns with modern society's requirements for corporate energy conservation and emission reduction, and it helps enhance the hotel's social image.

For hotels, heat recovery chillers are a multi-beneficial device. They not only meet the hotel's cooling needs but also allow the hotel to easily achieve free hot water supply, offering positive implications in terms of cost savings and environmental protection.
