Chromite Chromite is a crystalline mineral composed primarily of iron(II) oxide and chromium(III) oxide compounds. It can be represented by the chemical formula of FeCr 2 O 4.It is an oxide mineral belonging to the spinel group.The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4).

Spent Ore from Heap, Dump, and Vat Leaching. Spent ore consists of the material remaining in either dump or heap leach piles when leaching ceases. Spent ore from heap, dump, and vat leaching may contain residual lixiviant and other constituents of the ore. Some operations may refer to wastes from vat leaching operations as tailings.

An ore is a rock or mineral that has enough metal in it to make it worth extracting. Mining copper About 200 s ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (ndida mine) and Indonesia (Grasberg mine
