Acid mine drainage (AMD) is the acidic water produced when rock containing sulphide minerals comes into contact with water and oxygen. Besides having a low pH, such water often contains high concentrations of dissolved solids, and often poses a serious threat to groundwater quality which, in turn, can affect drinking water 1 AMD destroys aquatic life and the problems can be long term some

APPENDIX B POTENTIAL ENVIRONMENTAL IMPACTS OF

mining industry is the formation of acid drainage and the associated mobilization of contaminants. Commonly called acid mine drainage (AMD) or acid rock drainage (ARD), acid drainage primarily depends on the mineralogy of the rock material and the availability of water and oxygen. Acid drainage is generated at both abandoned and active mine sites.

Beneficiation of pulp mill waste green liquor dregs

Acid mine Drainage (AMD) is a low pH, sulphate and heavy metal rich leachate that is produced from oxidation of sulphide bearing minerals commonly found in the host rocks of some mineral ores. The pH augmentation, and sulphate and metal removal in AMD is often achieved by adding alkaline reagents in it.

cimfr.csircentral

The main cause of acid mine drainage is the occurrence Of pyrite and sulphide minerals with the rock of coal seams. During mining these sulphide minerals get exposed to air and mine water. then oxidation and hydrolysis results in the generation of acid mine drainage. The low pH value Of the discharge mine water results in the further

Technical Document: Acid Mine Drainage Prediction

Acid Mine Drainage Prediction compares acid rock drainage factors of waste rock piles and tailings impoundments. In examining this table, it is important to note that diffusion of oxygen into water is slow and, therefore, oxidation of iron sulfide is inhibited until the water level drops, which can occur periodically or seasonally in some cases.
