摘要
超基性岩型硫化镍铜多金属共生贫矿石中矿物种类繁多，镶嵌关系复杂，伴生有什金属丰富。该矿石的分选，尤其是精矿降镁难度大．研制了一各以Ａｓ—４为捕收起泡剂分速浮选，中矿添加ＡＴ─４、ＡＴ—５等调整剂集中再选的ＢＦＰ全混合浮选新工艺，获得了良好的指标．
There exist a grcat varicty of mincrals adn associated valuable metals in a ultrabasic multimeta poor nickel-copper sulfide ore,and the relation of the minerals are complex.It is dif ficult it bencficiate the ore,specially to remove MgO-containing mincrals from flotation concentrate. Researchers have developed Researchers have developed a novel bulk flotation technological process(BFP),that is, bencficiating mineral particles according to their flotation velocity using a As-4 collector-frother,and centralized to separate again using AT-4,AT-5 as modificrs. An excellent metallurgical performance has been obtained when the new process is employed to beneficiate the poor ore.
