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

紫硫镍铁原生粒度较大,被认为是最易浮选的硫化铜镍。

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

铁很，含钴，在硫化块体中成稠密的斑块。

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

同时，铁表面初始氧化产如单质硫和硫化被还原，亲水性增强。
