用氢氧化钠浸出含钴高砷铁渣中砷的试验研究

Leaching of Arsenic from Cobalt-containing Arsenic and Iron Slag With Sodium Hydroxide

研究了用氢氧化钠浸出钴冶金过程中产出的高砷铁渣中的砷。结果表明,在高温高碱性条件下,砷浸出率达98%以上,可实现与钴、铁的分离。

Leaching of arsenic from arsenic and iron slag obtained from cobalt metallurgy with sodium hydroxide has been studied. The results show that the leaching ratio of arsenic is more than 98% under the conditions of high temperature and high alkalinity, the separation of arsenic from cobalt and iron can be achieved.
