chalcocite

Oxide copper minerals are mainly malachite, the second is chrysocolla, followed by a small amount of azurite; and sulfide copper minerals are mainly bornite, followed by chalcocite and covellite, and a small amount of chalcopyrite.

氧化铜矿物主要为孔雀石，其次是硅孔雀石，少量蓝铜矿；硫化铜矿物主要是斑铜矿，其次是辉铜矿和铜蓝，少量黄铜矿。

The major primary metal minerals of ore are chalcocite and bornite, and the secondary metal minerals are malachite and azurite, etc. Ore texture and structure are simply, the ores are mainly in granular crystalline and dissolution textures and infection cementation structures.
