硫化铁矿

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

黄很多，并且含钴，在块体中成稠密斑块。

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

紫镍原生粒度较大,被认为是最易浮选铜镍。

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

同时，黄面初始氧产如单质和多被还原，亲水性增强。
