铊在有色冶炼过程中的行为、危害及防治

The Behavior Harm and Prevention of Thallium in Nonferrous Attractive Metallurgy

铊及其化合物具有许多优异性质,使其具有很高的使用价值,在农业、医学、电子仪表,以及化工等各领域得到广泛的使用。铊主要是从铜、铅、锌冶炼过程中产生的烟尘、炉渣,和生产纸浆涤泥中综合回收,而通过采—选—冶的方式从铊独立矿中获取铊的情况非常少。因此,弄清铊在有色冶炼过程中的行为,是从冶炼过程中综合回收铊、防止铊污染的前提。文章简介了铊在选矿、有色冶炼过程中的行为、危害,并提出了相应的防治措施。

Thallium and its compound have many excellent characters, which makes it has high use value and be widely used in many kinds of fields, such as agriculture, medicine, chemical electro-instrument, and so on... Thallium is seldom directly gained by mining-concentrationsmelting from thallium ore, it mainly com- prehensive recovery from the soot and slag produced by copper, lead, and zinc attractive metallurgy, and also from pulp producing mud. So,make clear the behavior of thallium in nonferrous attractive metallurgy is prerequisite to recycle thallium and prevent its pollution. In this paper, the behavior of thallium in mineral process and nonferrous attractive metallurgy is produced, and a series of corresponding measures are put forward.
