随着铜钴矿物的不断开采，高品位、易处理铜钴矿资源的日益减少，低品位铜钴矿的开发利用越来越受到重视.低品位铜钴矿中有较多杂质金属离子，为了提高有价金属浸出率的同时抑制杂质金属离子的浸出，实验探讨温度、酸量、固液比、反应时间等因素对各金属离子浸出率的影响.最佳浸出工艺为：以盐酸为浸出液，盐酸总酸量为理论量的1倍，矿物粒度100目，固液比为S/L=1∶4，浸出时间为1 h，温度30℃.

With the exploitation of Copper-Cobalt minerals,the Copper-Cobalt ore resources of high quality and easy processing have been declining. Developing low-grade Copper-Cobalt ore is payed more attention. However ,the low-grade Copper-Cobalt ore contains impurity metal ions. In order to improve the leaching of valuable metals and suppress the leaching of impurity metal ions,the experiments of the temperature,the amount of acid,solid-liquid ratio,reaction time were explored. The optimal conditions are as follows:the leaching solution is hydrochloric acid,the total amount of hydrochloric acid is one times of the theoretical amount,mineral particle size is 100 mesh,solid-liquid ratio of S/L is 1∶4,the leaching time is one hour,and the leaching temperature is 30℃.
