应用选择性较好的新型捕收剂和起泡剂，采用异步混合浮选新工艺，粗精矿与中矿分别再磨分选，解决了现场混合浮选生产工艺存在的综合回收金、钼等伴生矿物与铜硫分离条件的矛盾，显著地提高了伴生金、钼的选矿指标，并进一步优化了主金属铜的回收。新药剂、新工艺适应德兴铜矿的矿石性质，获得了巨大的经济和社会效益。 The application of a new selective collector and foaming agent, the use of asynchronous mixing flotation new technology, crude concentrate and ore were re-grinding and sorting, to solve the site mixed flotation process there is a comprehensive recovery of gold, molybdenum And other associated minerals and copper and sulfur separation conditions of contradictions, significantly increased associated gold, molybdenum beneficiation indicators, and further optimize the recovery of the main copper. New agents, new technology to adapt Dexing copper ore properties, access to a huge economic and social benefits.
