一、前言目前,国內外自电解鎳生产过程所产出的鈷渣中提取高純度鈷,在生产实践中虽然已有数种成熟的生产工艺流程,但所有这些流程均有以下的缺点: 1.流程长,工序多;过程反应速度慢,作业周期长。 2.金属回收率低,生产效率不高,設备庞大,劳动力消耗多。为了寻求一个流程短、金属回收率高、反应快、 I. Introduction At present, at home and abroad, high purity cobalt is extracted from the cobalt slag produced in the electrolytic nickel production process. Although there are several mature production processes in production practice, all of these processes have the following disadvantages: 1. Long process, process and more; process reaction slow, long cycle. 2. Metal recovery is low, the production efficiency is not high, large equipment, labor consumption. In order to find a short process, high metal recovery, fast response,
