Sea sand refers to sand and gravel in the ocean, which is formed by the scouring, rolling, collision and grinding of sea water. As an important marine mineral, sea sand has a wide range of uses. One of the most important uses is in large-scale construction projects, such as land reclamation, where the demand for sea sand is particularly prominent. In addition, sea sand also provides a certain substitute for river sand, meeting the needs of infrastructure construction such as buildings, roads, and bridges. Sea sand has many other uses. It can be used as the main raw material for machinery and foundry sand, and can also be used for grinding materials, sand cleaning, rust removal, descaling ceramics and refractory materials. Sea sand contains rich quartz sand, red stone, diamond, fine sand, magnetite, etc. These are all important industrial raw…

The purity of the quartz sand produced by the company can reach more than 99.6%, which can be used as raw materials for ultra-white glass, photovoltaic glass. According to the design plan, the proposed project is designed with 1 quartz ore wet crushing production line, 2 quartz ore dry crushing production lines and 1 refined quartz sand production line. 6,000 tons of quartz stone are wet crushed and 15,000 tons of quartz stone are dry crushed annually. After wet crushing and dry crushing, the quartz stone enters the refined quartz sand production line with the purchased quartz sand. After flotation and magnetic separation, a total annual production capacity of 25,009 tons of high-purity quartz sand is formed.

The ore preparation process of hydrosmelting is mainly ore washing and chromium removal. The raw ore is mainly low-grade limonite or mixed ore mixed with residual ore, which has the characteristics of high moisture content, high viscosity, and complex process. The washing equipment used in the laterite nickel ore washing process mainly includes roller screens, cylinder washers, cylinder scrubbers, trough washers, etc. However, some mines have begun to add MMD crushing before washing. Machine crushing to reduce wear and tear on the equipment after larger particles enter the ore washing equipment. The chromium removal equipment currently used is mainly hydrocyclone, spiral chute, shaker, etc. Due to the fine particle size of laterite ore, it is difficult for the material to settle. Therefore, high-efficiency concentrators are generally used for laterite ore slurry concentration. Some mines also use deep cone concentrators for…

This method uses high-purity quartz sand as raw material to produce solar-grade polysilicon. Select silica materials with a SiO2 content of more than 99%, and perform water quenching, crushing, screening, pickling, magnetic separation, and high-pressure ionization to make the purity of the silica particles reach 99.99. % or more to obtain high-purity quartz sand. Chloride the carbonaceous reducing agent and the graphite electrode in the submerged arc furnace at high temperature in the chlorination furnace to make the purity of the carbonaceous reducing agent reach more than 99.9999%; use carbon in the submerged arc furnace High-purity quartz sand is reduced with a high-quality reducing agent to produce silicon. During the production process, silicon liquid is regularly released from the submerged furnace; the obtained silicon liquid is injected into the holding furnace, and the product is directly subjected to high-frequency plasma…
