摘　　要：以铜冶炼厂的污酸为原料,采用沉淀分离、氧化酸浸、选择性萃取分离、结晶相结合的工艺生产铼酸铵,可使得污酸中的铼、铅、铜、砷铋等重金属得到有效回收及处置。为同行业从污酸提铼提供了一个新的思路。The waste acid copper smelter as raw materials by precipitation separation, oxidizing acid leaching, selective extraction and crystallization technology combined production of ammonium rhenium, the waste acid of rhenium, lead, copper, arsenic, bismuth and other heavy metals effectively recycling and disposal. It provides a new way for the industry to recover rhenium from contaminated acid.
