Arsenic Leaching From Iron Rich Mineral Processing Waste

Jan 29, 2007 This paper presents the effect of pH and redox potential on the potential mobility of arsenic As from a contaminated mineral processing waste. The selected waste contained about 0.47 g kg-1 of As and 66.2 g kg-1 of iron Fe. The characteristic of the waste was identified by acid digestion, X-ray diffraction and sequential extraction procedures.
