我厂是锌、钴为主要产品的冶炼厂。每年进厂原料锌精矿和钴硫精矿中含砷量是很高的,除主要产品和付产品中含少量砷外,绝大部份砷都进入三废中,严重污染环境。因此砷治理是我厂重要科研项目之一。砷在锌、钴冶金过程中可呈单质、化合物、金属互化物等状态分布在各种物料中,但多数在蒸馏缶渣和砷渣中,这是砷
I plant is zinc, cobalt smelter as the main product. Each year into the plant raw materials, zinc concentrate and cobalt concentrate contains arsenic is very high, in addition to the main products and products containing a small amount of arsenic, the vast majority of arsenic into the three wastes, seriously polluting the environment. Therefore, arsenic treatment is one of our important scientific research projects. Arsenic in zinc, cobalt metallurgy process can be a single substance, compounds, intermetallics and other states are distributed in a variety of materials, but most in the distillation of slag and arsenic residue, which is arsenic
