- Abstract: Mining disturbs geologic formations that took millions of years to form; once disruption has taken place, a variety of problems may arise, from physical hazards to pollution of water and soil. The main goal of this paper is to demonstrate the technical feasibility of ferric and ferrous ions in-situ removal from Acid Mine Drainage and to design suitable flowcharts that can be used to model in-situ neutralization. The principle is based on lime neutralization without agitation that consists of diffusion and neutralization of hydrogen ions within the solution, which will increase the pH and lead to diffusion and precipitation of ferric and ferrous ions. Experimental tests were conducted with raw Acid Mine Drainage solution from Randfontein Mine (Johannesburg, South Africa) and the method shows that it is possible to achieve about 90 - 98% efficiency for ferric and ferrous ions in-situ removal from Acid Mine Drainage., Conference proceedings
