What the metalloid mineral products that we say normally points to is mineral or the rock except any sort that economic value has beyond metallic ore, mineral fuel, mineral aggregate.
Metalloid mineral products is a kind of mineral products that uses the earliest for the mankind, the Shi Dao of Stone Age, zax, and Yangshao culture of The Neo-lithic Age (BC 5000 — 3000) ancient painted pottery, showed this adequately. The main metalloid mineral products that uses to place of the mankind at the beginning of 20 centuries has 60 kinds about, and amount to 200 kinds of above unexpectedly at present. As the development of modern industry, the sort of stone of mineral He Yan that can use for industry still will continue to grow.
Metalloid bed sort is various, the bed that be like phosphor, salt kind bed, asbestine bed, black lead bed, diamond bed and treasure jade bed are waited a moment, and widespread, make us possible abundantly tries to use. If the owner of ore ore deposit that makes metalloid deposit contains oxygen salt kind, give priority to with silicate, sulfate especially, take second place of phosphate, borate, oxide, halide and certain and natural element also can form deposit.
Of metalloid ore use means and metallic ore to differ. On industry, only a few metalloid ore is to use what extract and use certain metalloid element or its compound, if sulfur, phosphor, Potassium, boron is waited a moment, the industrial value of these ore basically depends on the processability of the content of useful element and ore is qualitative. And most metalloid ore is to use among them valuable mineral, mineral aggregate or petrosal directly certain physics, chemistry and engineering technology character. E.g. , diamond uses its hardness and burnish mostly; Mica is to use its insulating properties and diaphaneity, it can regard an electron as important raw material of industry; Crystal is to use its optics is waited a moment with the function that suppress report.
Current, metalloid mineral products is used more extensively in our country, basically be in the following respects:
1. Agricultural respect
People carries the yield of crop to rise, the phosphate fertilizer that is in a large number of farm is medium use to be produced by ore of phosphor, Potassium and potash fertilizer and agricultural small rare land, the bumper harvest that is agriculture made contribution.
2. Industrial respect
In glass, chemical industry, papermaking, balata, food, medicine, electron industry of electric, mechanical, plane, radar, missile, nuclear energy, sophisticated technology and optics, drill wait for a respect to also need breed various, have the metalloid mineral products of characteristic of special engineering technology. If silica and feldspar are the main raw material of production glass; Black lead uses as in the device of rocket, missile heat resistant material, use as in a lot of respects the lubricant of mechanical movement. Mica is electric, the indispensable electric insulating material in radio and aviation technology; Aluminous can make refine aluminium, production potash fertilizer and vitriolic raw material, also can use at pressworking, papermaking, painter course of study.
