Leaching of mineral sands is often referred to as a solid liquid multiphase reaction. The mineral surfaces covered in iron oxide in the most stable form Fe2O3 are contacted with sulphuric acid. This reaction involves sulphuric acid removal of the surface and the formation of iron sulphate Fe2(SO4)3. The feed is received from a...
