含砷物料的综合利用是有色冶金企业带普遍性的问题。由于铜、铅、锌、锡、锑、钨等矿床中多含有砷,致使大量的砷进入冶金企业。仅湖南、江西、广东、广西、云南五省各冶炼厂,每年由原料带入的总砷量即达五千余吨。在冶炼过程中它们分别进入烟尘、
The comprehensive utilization of arsenic-containing materials is a non-ferrous metallurgical enterprise with a general problem. As a result of copper, lead, zinc, tin, antimony, tungsten and other deposits contain arsenic, resulting in a large number of arsenic into the metallurgical enterprises. Only the smelters in five provinces of Hunan, Jiangxi, Guangdong, Guangxi and Yunnan Province each year brought about 5,000 tons of total arsenic from raw materials. In the smelting process, they respectively enter the smoke and dust,
