湿法冶金技术在滇中铜矿石处理中的应用

Application of Hydrometallurgical Process in Treating Copper Ore From Middle Regions in Yunnan Province

用现代湿法冶金技术中的硫酸堆浸-萃取-电积工艺处理低品位、复杂难选冶氧化铜矿,用硫酸化焙烧-浸出-电积工艺处理硫化铜矿,生产合格电解铜,成本大大降低,可获得较好的经济效益和社会效益。采用此工艺处理滇中地区氧化铜矿和硫化铜矿,既解决了环保问题,又提高了铜回收率。

By the technology of advanced copper hydrometallurgy which is heap leaching-solvent extraction-electrodeposition for treating low grade copper oxide ore or roasting-leaching-electrodeposition for treating copper sulphide ore, more eligible electrolytic copper is produced, at the same time, produce cost is decreased. When the technology is used for treating copper oxide ore and copper sulphide ore from middle regions in Yunnan province, not only environment protection is improved, but also recovery of copper is increased remarkably, high economic benefit and environmental benefit are acquired.
