我国打破锌精矿加压技术国外垄断25年来,硫化锌精矿加压湿法冶金技术一直被加拿大Hudson Bay一家公司垄断。日前,云南省科技厅向外界宣布,云南冶金集团总公司已经掌握了该领域冶炼技术,并取得了自主知识产权。该项目技术负责人——云南省冶金集团总公司副总工程师王吉坤介绍,该项目自主开发了氧压浸出技术,对硫化锌精矿直接进行浸出,经净化电积产出锌锭,矿中的其它有价金属得到很好回收。硫以元素硫形态产出,锌的生产不必受
China to break the monopoly of zinc concentrate pressure technology foreign monopoly over the past 25 years, zinc sulfide concentrate hydrometallurgy technology has been monopolized by a Canadian company Hudson Bay. Recently, Yunnan Science and Technology Department announced to the outside world that Yunnan Metallurgical Group Corporation has mastered the smelting technology in this field and has obtained independent intellectual property rights. The project manager in charge of technology - Yunnan Metallurgical Group Corporation, Wang Jikun, deputy chief engineer introduced the project developed its own oxygen pressure leaching technology, the direct leaching of zinc sulfide concentrate, the purification of electrowinning output of zinc ingot, the mine Other valuable metals are well recycled. Sulfur to elemental sulfur form output, zinc production do not have to suffer
