在分选含黄铁矿铜-锌矿石时,无尾矿工艺的建立要预先研制出一些能保证不仅回收铜、锌和黄铁矿精矿,也能分离出国民经济中可以利用的非金属矿物产品的流程。在这种情况下,就完全不必建立尾矿场,并可缩减用于环境保护的费用。实现无尾矿工艺的条件之一,是要把最大量的黄铁矿选入高质量精矿,这样就避免黄铁矿与非金属部分掺混,可以保证达到建筑企业提出的对非金属材料的要求。 In the sorting of pyrite-containing copper-zinc ores, the establishment of a tailings-free process has been pre-developed to ensure that not only the recovery of copper, zinc and pyrite concentrates, but also the separation of non-metals that can be utilized in the national economy Mineral product flow. In this case, there is absolutely no need to set up tailings and reduce the cost of environmental protection. One of the conditions for achieving tailings-free process is to select the maximum amount of pyrite into high-quality concentrate so as to avoid the blending of pyrite and non-metallic parts, to ensure that the non-metallic materials Request.
