Chromium is the brittle, lustrous and hard chemical element that belongs to the group of spinel. Chromite grains are commonly found in large mafic intrusions and are also found in metamorphic rocks on the earth's crust. Chromite, which is an iron chromium oxide (FeCr2O4) is the only ore present to produce the element chromium.

Sulfur Mining. Sulfur attaches to metal ions, creating a number of significant sulfide ore minerals such as galena (lead sulfide), pyrite (iron sulfide), chalcocite (copper sulfide), and sphalerite (zinc sulfide). Mined sulfur is mostly from salt domes or bedded deposits. The vast majority is produced as a by-product of oil refining and natural
