| Use | Zinc silicate chemical formula Zn2SiO4 is summarized. Molecular weight 222.84. Colorless three-party crystals. The specific gravity was 4.103. Melting point 1,512 °c. Soluble in hydrofluoric acid, insoluble in water and dilute acid. Decomposition in case of hydrogen chloride. It exists in the form of zinc in nature. From zinc oxide and silica (2:1) mixture by high temperature heating. For the manufacture of fluorescent screen, etc. In the process of flotation enrichment of zinc silicate, due to the close floatability of zinc silicate and its impurity minerals such as calcium carbonate, quartz and so on, in the grinding process, the impurity minerals are easy to form slime, which affects the flotation performance of zinc silicate, making it difficult for zinc silicate minerals to be enriched by flotation. Even if it can be enriched by flotation occasionally, the structure of the process flow is complex, the development and utilization of zinc silicate ore are limited due to the variety and amount of reagents, high production cost and low flotation index. |
