国外某氧化铜矿选矿工艺研究

Study on the Flotation Craft of Copper Oxide Ore in Abroad

文章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、粒度特性、赋存状态和嵌镶关系的基础上,依试样性质,通过探索性试验确定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,为合理利用有限的矿产资源,提供了可靠的设计依据。

Learned from the study on mineralogy of the samples, a large amount of condition tests have been carried out on the basis of the chemical component, mineral composition, structure, storing states and mosaic relation of the samples to determine the optimum process and technological parameters. Then, the closed circuit trial have been taken and got a better classification index. It has provided the detailed design basis for making use of the lim- ited mineral resources rationally.
