The occurrence of Sphalerite and Useful Mineral Association. Sphalerite is often associated with minerals such as fluorite, chalcopyrite, marcasite, galena, pyrite, quartz, barite. Sphalerite, also known as blende or zinc blende, is the major ore
Flotation is carried out in Maxwell cells, retro fitted with Outokumpu mechanisms, and in CESL column cells supplied by Canadian Process Technologies. On stream analyzers, providing real time assay information, control the flotation circuit. The result is a zinc concentrate at 55.2 Zn, 3 Pb and 137g/t Ag and a lead concentrate at 56.1 Pb, 11.7 Zn and 435g/t Ag. The concentrates are

Ball Mill. Ball mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind able materials.
FeS 2 has been prepared so far by different methods such as thermal sulfuration mechanochemical milling but the conversion efficiency of iron disulfide solar cells has been low because FeS 2 can crystallize not only into a cubic pyrite structure but also into an orthorhombic marcasite structure with low band gap Eg 0.34 eV .
A characteristic of this mineral is its peculiar tubular morphology. On the origin of the tubes, Moëlo et al 2014 propose that this is caused by capillary forces acting on very thin lamellar crystallites around gas bubbles or liquid droplets. The unit cell of tubulite is very close to those of sterryiteand parasterryite.
