硫化铁矿

Pyrite is more abundant and cobaltiferous and occurs in heavy patches in the sulfide mass.

黄铁很，并且含钴，在块体中成稠密的斑块。

Primary violarite has comparatively big particle size,and it is considered the easiest flotation copper-niekle-sulphide ore.

紫镍铁粒度较大,被认为是最易浮选的铜镍。

While the reduction of the initial oxidized products on pyrite surface such as polysulphide and free sulphur can improve its hydrophilicity.

同时，黄铁表面初始氧产如单质和被还，亲水性增强。
