摘要
研究了金川镍精矿加压一步全浸镍、钴、铜新工艺,浸出液中和除铜后萃取分离镍钴,镍、钴、铜的浸出率可分别达到99.5%、98%和98%以上。该工艺与硫酸选择性浸出相比具有金属浸出率高、分离彻底、易分别回收等优点。
Experiments have been conducted to extract nickel, cobalt, copper by pressure leaching from nickel concentrate. Nickel and cobalt can be separated by solvent extraction from leaching solution after copper removal, and the leaching rate of Ni, Co, Cu can reach 99.7%, 95%, 98% respectively. Compared with selective acid leaching, this process has the advantages of high extraction, completely metal separation and metal recovery easily.
