摘　　要：河南某低品位白钨矿(WO_(3)含量0.062%)选矿厂以Y1为抑制剂,但提质效果不理想。为改善该状况,进行了大量的抑制剂优选试验。结果表明,SH系列抑制剂对该白钨矿适用性较差,提升粗精矿品位效果不明显;WT系列抑制剂适用性强,可有效提升白钨矿粗精矿品位;相比于单一抑制剂,WT系列抑制剂组合使用对白钨矿粗精矿品位提升效果更明显;组合抑制剂SG-1与现场抑制剂Y1相比,在用量少120 g/t的条件下,白钨矿粗精矿WO_(3)品位由0.805%提高至1.257%,回收率仅下降0.46个百分点。SG-1对低品位白钨矿粗精矿品位的强化提升效果优良。A low-grade scheelite(WO_(3)content of 0.062%)beneficiation plant in He’nan uses Y1 as an inhibitor,but the quality improvement effect is not satisfactory.In order to improve the situation,a large number of inhibitor optimization experiments have been carried out.The results showed that the SH series inhibitors have poor applicability to the scheelite,and the effect of improving the rough concentrate grade is not obvious.The WT series inhibitors have strong applicability and can effectively improve the grade of scheelite rough concentrate.Compared with the single inhibitor,the combined use of WT series inhibitors has a more obvious effect on improving the grade of scheelite rough concentrate.Compared with the on-site inhibitor Y1,the combined inhibitor SG-1 has a lower dosage of 120 g/t.The WO_(3)grade of the rough concentrate was increased from 0.805%to 1.257%,and the recovery rate only decreased by 0.46 percentage points.SG-1 has an excellent effect on enhancing the grade of low-grade scheelite rough concentrate.
