Abstract
Recovering gold form arsenic bearing gold mine through floatation has always been an important research subject, the gold ore contains 2.40 g/t of gold and content of arsenic was 1.2% in Hebei, cannot achieve good product indexes, in order to improve the efficiency of resource use, lime was adopted to control the pH value of pulp, NaHSO3was added to inhibit the arsenic, the floatation of gold was carried out priority. The gold concentrate contain 65.63g/t with the recovery was 89.92% and the content of arsenic was only 0.07% after closed-circuit experiment, that results means the product indexes were improved greatly compare the field product now.
