Abstract

In order to realize the comprehensive utilization of cobalt resource, a review was introduced on the recovery method of cobalt from the cobalt converter slag and its research progress and application. During the smelting, most cobalt was chemically dissolved in the converter slag.On the basis of its dissolved and present status in converter slag, the flotation, pyrometallurgy, wet separation, extraction, bioleaching separation and recovery methods were introduced. The advantage and limit of various separation and recovery methods were also discussed. Among them, both the solvent extraction which is characterized by high selectivity, high recovery rate, simple flow, continuous operation and easy to realize automation, and the microbial leaching which is characterized by smallest pollution, low cost and high efficiency have promising application future.
