摘要
针对某含砷难选锌铁矿石,采用浮—磁流程,石灰为pH值调整剂,并配合亚硫酸钠抑制毒砂,捕收剂为选择性好的硫氨酯,获得了较好的试验结果。
Aimed at a certain refractory zinc-iron ore containing arsenic, a flowsheet of flotation-magnet ic separation technology was adopted , lime was used as pH value adjustment, and arsenopyrite was suppressed by coordinate with sodium sulfite, iso-octyl mercaptoacetate was used as collector which has good selectivity. The experiment has got a better result.
