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

紫硫镍生粒度较大,被认为是最易浮选的硫化铜镍物。

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

黄很多，并且含钴，在硫化物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，黄面初始氧化产物如单质硫和多硫化物被还，亲水性增强。
