Abstract
As a part of comprehensive utilization of concentrate linnaeite, this paper mainly discussed the theoretical bases and technical process conditions of separation of cobalt and nickel by two-section extraction with N235 and extraction of copper with Lix984 after changing sulfate system containing cobalt into chloride one, and solved the difficulty of removing Mg2+. Pure CoCl2 solution for preparation of cobalt soaps was produced in this way, and chemical products of copper and nickel such as CuCl2 · 2H2O,NiCl2 · 6H2O were by-produced. It has many advantages, such as fewer reagents, high recovery yield of metals. It is an economical way for comprehensively recovering valuable metals of concentrate linnaeite.
