江西赣州钴冶炼厂在生产过程中,每年产生钨碱浸渣1000t以上,硫铁矿烧渣2500t以上,废酸约2000m~3,析钴和萃取母液3000t以上。此外还有含砷烟气。该厂综合利用这些“废渣”、“废液”、“废气”收到了很好的社会、经济效益。 几年来该厂开展综合回收的主要项目: 1.用电炉法提纯粗三氧化二砷 投产初期在冶炼砷钴矿时,由于时间紧促,对其副产品粗砷灰,一直是采取库存堆放处理。到1980年,粗砷灰累计已堆积8000t
Jiangxi Ganzhou cobalt smelter in the production process each year produces more than 1000t tungsten alkali leaching residue, pyrite slag 2500t above, waste acid about 2000m ~ 3, analysis of cobalt and extraction mother liquor 3000t above. In addition there is arsenic fumes. The plant comprehensive utilization of these “waste residue”, “waste”, “waste gas” received a very good social and economic benefits. In recent years, the plant to carry out comprehensive recovery of major projects: 1. Electric furnace purification Crude arsenic trioxide in the early commissioning of smelting arsenic and cobalt ore, due to the urgency of time, its by-product coarse arsenic ash, has been to take stock piling up. By 1980, crude arsenic accumulated 8,000 tons
