pH对胺类捕收剂反浮选脱硅的影响

摘要

矿浆溶液的pH是影响浮选指标的重要因素之一,研究了三种胺类捕收剂在用量一定时,pH对云南某中低品位硅质胶磷矿脱硅的影响.试验结果表明,胺类药剂反浮选脱硅较适宜的pH范围为7.0～8.5.%The pulp pH is an important factor affecting flotation. In this paper, effect of pH was studied on three kinds of amine-collector with the their amount in a certain time in flotation of silicon separation of Yunnan mid-low grade cellophane. The results show that the pHrange of 7.0-8.5 is suitable for amine collector in reverse flotation process of silicon separation.
