Acid Mine Drainage an overview ScienceDirect Topics

Acid mine drainage describes a natural process produced when the mining activities expose sulfur-bearing minerals (mostly iron sulfides) to atmospheric oxygen, moisture, and acidophilic iron-oxidizing bacteria, resulting in sulfuric acid, dissolved iron, and precipitation of ferric hydroxide. The sulfuric acid dissolves heavy metals from mined materials and forms an acidic pH solution with elevated

THE USE OF SULPHURIC ACID IN THE MINERAL SANDS

2011-7-5  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 HAL bin which feed two reactors A, B at 12 t/hr and 27 t/hr respectively. Before entering the reactor the feed is preheated to 160 oC through a fluidized bed and gravity fed to the feed chute where sulphuric acid
