一、绪言在铜-锌矿石浮选方面,历来通常采用黄药或黑药做为捕收剂,在利用这些捕收剂的同时,要考虑选择适当的pH值或选择适当的抑制剂,以使铜-锌矿物分离。即在一般的碱性介质中,使用适量的氰化钠、氰化钾、硫酸锌、硫化钠、亚硫酸钠等抑制锌矿物,优先浮选铜的方法。如众所知,锌矿物有被矿液中微 I. INTRODUCTION In the copper-zinc ore flotation, xanthate or black drug have traditionally been used as collectors. While using these collectors, it is necessary to consider selecting the appropriate pH value or selecting the appropriate inhibitor Copper - zinc mineral separation. That is, in a general alkaline medium, a suitable amount of sodium cyanide, potassium cyanide, zinc sulfate, sodium sulfide, sodium sulfite and the like is used to suppress the zinc mineral and preferentially float the copper. As we all know, zinc minerals are micro-minerals
