从试样的工艺矿物学研究出发,在查明试样化学成分、矿物组成、结构构造、赋存状态和嵌布关系的基础上,依据试样性质确定浮选试验方案与工艺流程,并进行了大量的条件试验,以确定最佳的工艺参数,尔后开展了全流程闭路试验,取得了良好的分选指标,其中铅精矿品位60.01%、回收率90.35%,锌精矿品位49.15%、回收率87.08%,硫精矿品位41.15%、回收率82.55%。为合理利用国家矿产资源,提供了详实的设计依据。
Based on the process mineralogy of the sample, on the basis of ascertaining the chemical composition, mineral composition, structural structure, occurrence state and interlacing of the sample, the flotation test scheme and technological process are determined according to the properties of the sample, A large number of condition tests were conducted to determine the best process parameters. Afterwards, a full-process closed-circuit test was carried out and a good sorting index was obtained. The grade of lead concentrate was 60.01%, the recovery rate was 90.35%, the grade of zinc concentrate was 49.15% The recovery rate was 87.08%, the concentrate grade was 41.15% and the recovery rate was 82.55%. In order to make rational use of national mineral resources, it provides a detailed design basis.
