ZincOx

Zinc generally occurs as the zinc sulphide mineral, sphalerite. At the mines the ore is crushed and milled then undergoes flotation which is a process which separates out the sphalerite grains to produce a mineral concentrate Zinc released to the environment follows a cycle (figure 1) in which zinc from mineral ore bodies is converted through extraction and refining processes from its mineral state (mostly sphalerite ore, zinc sulfide) into the metallic state.
