一、前言炼铜转炉渣含钴一般为0.2～0.5%;为回收这部分钴,过去一直采用电炉贫化,富钴冰铜硫酸化焙烧,或高压酸浸制取含钴溶液以获得钴产品。由于种种问题,总是难于实现工业化生产。铜陵有色金属公司第一冶炼厂,在厂党委领导下,以阶级斗争为纲,大搞综合利用,将转炉渣第一次浮选尾砂(其钴品位为0.25～0.28%,铜品位0.7～0.9%), I. Introduction Copper converter slag containing cobalt is generally 0.2 ~ 0.5%; for the recovery of this part of cobalt, the past has been depleted by electric furnace, cobalt-rich matte sulfated roasting, or high-pressure acid leaching take cobalt solution to obtain cobalt products . Due to various problems, it is always difficult to achieve industrialized production. Tongling Nonferrous Metals Company, the first smelter, under the leadership of the factory party committees, to class struggle as the key link, make comprehensive utilization of the converter slag the first flotation tailings (cobalt grade 0.25 ~ 0.28%, copper grade 0.7 ~ 0.9%),
