摘要
主要针对我国多金属硫化物勘探合同区样品产出的精矿开展冶炼工艺方案研究,考察其冶金性能,综合回收其有价金属。通过试验研究,富锌多金属硫化物精矿经焙烧-酸浸后,锌和铜浸出率可分别达到99.22%和96.71%,贵金属主要富集于浸出渣中,为我国大洋多金属硫化物的冶金技术开发提供依据。
Metallurgical properties of zinc concentrate from oceanic polymetallic sulphides of COMRA were studied.Resources of oceanic polymetallic sulphides were recovered synthetically and maximized.Through experimental study,leaching rate of zinc and copper in zinc concentrate can reach 99.22%and 96.71%respectively and precious metals enriches in leaching residue in the process of roasting-leaching,which provides basis for metallurgical technology development of oceanic polymetallic sulphides.
