Abstract
A significant environmental issue, and one of increasingly widespread interest over the past decade, is that of acid rock drainage (ARD) from mineral processing tailings deposits and mine waste piles. Acid rock drainage is caused by the oxidation of sulfide-bearing minerals followed by leaching and mobilization of toxic elements. This paper describes research by the Bureau of Mines demonstrating the feasibility of reprocessing the tailings and removing the sulfidic material, which is the ARD source, using conventional mineral processing methods.
