硫化铁矿

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

黄铁矿很多，并且含钴，在化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.

铁矿生粒度较大,认为是最易浮选的化铜矿。

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

同时，黄铁矿表面初始氧化产如单质和多化，亲水性增强。
