This effect is comparable with the activation of sphalerite and pyrite by copper sulfate. Thus, pyrite floats a good way as copper sulfides (or lead). After such surface activation of pyrite with copper cations, selective depression with traditional methods is much more difficult (added cyanides).

Sphalerite Mineral information, data and localities.

Sphalerite Group. Sphalerite, also known as blende or zinc blende, is the major ore of zinc. When pure (with little or no iron) it forms clear crystals with colours ranging from pale yellow (known as Cleiophane) to orange and red shades (known as Ruby Blende), but as iron content increases it forms dark, opaque metallic crystals (known as Marmatite).

Sphalerite Article about sphalerite by The Free Dictionary

Sphalerite. Varieties rich in Fe are known as marmatite, while the colorless and nearly colorless varieties are known as cleiophane. The structure of sphalerite is one of very dense cubic packing of S atoms with the tetrahedral interstices occupied by Zn atoms. The hexagonal modification of ZnS is called wurtzite.

Separation Process of Chalcopyrite, Galenite, Sphalerite

2. The Separation of Galenite and Sphalerite. When separating the galenite and sphalerite, galenite is always enriched at first and then sphalerite will be enriched. In the separation of galenite and sphalerite, Xanthate or black catching agent is usually used as collector. And NaCN,KCN, ZnSO 4, Na 2 OS 3, Na 2 S 2 O 3 are always be used as inhibitors. And copper sulphate always is used as activator.
