矿石

The simthsonite name derives from English mineralogist James Smithson(1765-1829), who identified two different minerals smithsonite from hemimorphite in 1807, both have long been confused as same mineral, called calamine, used to produce brass, mixed with cupper.

18世纪末在欧洲，人们称用于冶炼黄铜的，和铜矿混在一起的锌矿石为菱锌矿，实际上那是的"菱锌矿"里面混杂了含水硅酸锌、异极矿和碳酸锌。由于产状大多时葡萄状，所以很难区分两种矿物。

Direct cyanidation will be taken and roasting process will not be necessary after removal of arsenic.

难浸金矿石和精矿用常规氰化法直接提取时，不能有效地回收金，因此，必须经过预处理。

By the end of 1998, minerals that had been discovered, confirmed and explored included: cyanite, silex ,quartz,xanthoconite, others that need proving up and exploring included: mica, phosphorite, diamond, rutile, crude oil, kalium ore, etc.

至1998年底，发现、探明并已开发利用的矿种有：蓝晶石、硅石、石英砂、黄砂，有待探明和开发利用的矿种有云母、磷矿石、金刚石、金红石、石油、钾矿石等。

The ore mainly has cyclopean granular texture andmassive and laminar structures.

矿石以镶嵌粒状变晶结构，块状和纹层状构造为主。
