摘要
根据甘肃某含砷金矿石特性,对其进行了回收金及金、砷分离试验研究。结果表明:采用混合浮选流程,水玻璃作调整剂、丁基黄药作捕收剂、过氧化钙作抑制剂的条件下,可得金品位153.97 g/t,金回收率76.18%,含砷2.32%的金精矿。
The experimental study of gold recovery, separation of gold and arsenic was carried out according to the characteristics of one arsenic bearing gold ore in Gansu. The results show： the mixed flotation flow is adopted, the water glass is serves as the regulator, the sodium n-butylxanthate is serves as the collecting agent, the calcium peroxide is serves as the inhibitor depressor, under the above men- tioned conditions, we can get the gold concentrate with the 153.97g/t gold grade, the 76. 18% gold recovery rate, and 2. 32% arsenic con-
