滑石是一种含水的硅酸镁矿物,分子式为Mg_3[Si_4O_(10)](OH)_2。我国滑石储量1.8亿多吨,产量的年增长率为6％,无论其储量、产量还是出口量在世界上均首屈一指。滑石的矿床类型一般有两种。一种是镁质碳酸盐中的滑石矿床;另一种是超基性岩中的滑石矿床。我国的滑石矿床基本上属于第一种类型,约占滑石总储量的96％,其年产量占全国滑石产量的90％以上,同时也是近年出口滑石的主要矿床类型。
Talc is an aqueous magnesium silicate mineral, the formula is Mg_3 [Si_4O_ (10)] (OH) _2. China’s talc reserves of 180 million tons, annual output growth rate of 6%, regardless of its reserves, production or export volume in the world are second to none. There are generally two types of talc deposits. One is talc deposit in magnesian carbonate and the other is talc deposit in ultrabasic rock. China’s talc deposit is basically the first type, accounting for 96% of the total reserves of talc, its annual output accounts for more than 90% of the national talc production, but also the main type of export of talc in recent years.
