摘　　要：通过研究北山铅锌矿矿石中不同矿物在高碱性介质中的浮选特性和分选条件，提出了处理该类矿石的分选新工艺。该工艺的基本点是：将石灰与乙硫氮同时加入磨矿机中，利用这两类药剂在高碱性介质中（ｐＨ＝１２８～１３０，矿浆中有效ＣａＯ含量为１０００～１２００ｍｇ／Ｌ）对矿物选择性的作用，不用其他锌抑制剂，实现了方铅矿与闪锌矿、黄铁矿的有效分离。生产实践证明，新工艺不仅在产品质量及金属回收率方面比原工艺有了显著提高，而且药剂用量也大幅度降低。The flotation characteristics and conditions of Beishan minerals in strong alkaline media are studied. Based on this, the authors give a new separation technique for this type of ores. Its basic separation principle is that lime and DDTC are added to mills at the same time to achieve effective separation of galenite from false galena and pyrite by means of the selectivity of the two reagents for minerals in high alkalinie media. The production practice show that compared with the original technique, the new technique can improve remarkably product quality and metal recovery and reduce greatly reagent dosage.
