Product introduction:

Producing high purity silica sand involves a multi-step process that starts with the extraction of silica-rich raw materials such as quartz sandstone or quartzite. The raw materials are then processed through a series of steps to remove impurities content.

1. Washing: Washing with water to remove impurities such as clay, and other minerals. 

2. Crushing and Grinding: The raw materials are first crushed into smaller pieces using a crusher or grinder. This increases the surface area of the material, making it easier to remove impurities in subsequent steps.

3. Drying: After washing, the silica sand is dried using a dryer or oven. This step removes any remaining water from the sand, making it easier to handle and process.

4. Screening: The dried silica sand is then screened to separate it into different particle sizes. The desired particle size depends on the intended application of the silica sand.

5. Classification: The silica sand can be further classified using various methods such as magnetic separation, electrostatic separation, and flotation to remove specific impurities.

6. Chemical Treatment: In some cases, the silica sand may be treated with chemicals to remove specific impurities or to modify its properties. For example, the silica sand may be treated with acid to remove iron oxide impurities.

7. Final Processing: The processed silica sand is then subjected to a final quality control check to ensure that it meets the desired purity and specifications.

The specific steps involved in producing high purity silica sand may vary depending on the quality and composition of the raw materials, the desired purity level, and the intended application of the silica sand.

Application field:

High purity White Silica Quartz Sand has a very wide range of applications, such as glass industry, ceramic production, metallurgical casting, construction and so on. It is also used in high-tech fields, such as the semiconductor industry and aerospace.

• Glassmaking: Silica sand is the main ingredient in glass production. It is melted with other materials to form a clear, transparent material that is used in windows, bottles, and other products.

• Ceramics: Silica sand is also used in the production of ceramics, such as tiles, pottery, and sanitary ware. It is added to the clay to give the final product strength and durability.

• Foundry: Silica sand is used in foundry applications to create molds for metal castings. It provides a smooth, hard surface that can withstand the high temperatures of molten metal.

• Construction: Silica sand is used in construction as an aggregate in concrete and asphalt. It provides strength and stability to these materials.

• Water filtration: Silica sand is used in water filtration systems to remove impurities from water. The sand's sharp edges trap and remove contaminants, leaving behind clean, clear water.

• Electronics: Silica sand is used in the production of semiconductors and other electronic components. It is a key ingredient in silicon, which is a vital material in the electronics industry.

• In addition to these specific applications, high-purity 99% silica sand is also used in a variety of other industries, including:

• Chemical manufacturing

• Oil and gas production

• Paint and coatings

• Plastics

• Cosmetics
