从海底热液硫化物中回收铜的可选性试验研究

Experimental study on copper beneficialbility of aseafloor hydrothermal sulfide ore

大洋海底埋藏的热液硫化物矿产资源非常丰富,是人类未来开发利用的潜在资源。本文在对西南印度洋某海域的热液硫化物进行矿石性质研究的基础上,开展了回收铜的可选性试验研究,初步确定了回收硫化铜的浮选工艺流程,实现了对样品中硫化铜矿物的合理回收,为海底热液硫化物矿产资源矿区的申请和圈定提供了依据。

Ocean-buried hydrothermal sulfide mineral resources are very rich,which are potential resources for human exploitation and utilization in future.On the base of mineralogical study on hydrothermal sulfide ore from the Southwest of the Indian Ocean,preliminary copper sulfide flotation process was determined after beneficiability study.The study achieved reasonable recovery of copper sulfide and provided a basis for decision-making for application and delineation of the mining area of seafloor hydrothermal sulfidemineral resources.
