The Role of Arsenic in the Mining Industry

Arsenic may also be obtained from copper, gold, and lead smelter flue dust as well as from roasting arsenopyrite, the most abundant ore mineral of arsenic. However, arsenic is not recovered from these sources but is rather disposed of in an environmentally safe

Arsenic Pyrite Gold Extraction by Alkaline Leaching Oxidation

Leaching of HighGrade Ore. The effects of NaOH concentration, oxygen pressure, temperature, reaction time, and percent solids on extraction of arsenic from ore A are given in table 4. The ore contains 61 pct arsenopyrite, and the stoichiometric NaOH for complete extraction of arsenic is 1.88 mol of NaOH per 100 g ore according to equation 1.
