Review of Arsenic Pollution and Treatment Progress in Nonferrous Metallurgy Industry

摘要

Arsenic pollution in nonferrous metallurgy industry and its control and utility techniques were summarized. The arsenic emission from the process of metallurgy industrial production, which is main sources of Arsenic pollution, is harmful to environment. The treating methods and the present utilization of As-containing soil, slag and tailings, dust and As-contaminated wastewater are introduced in this paper. And also the development and application and future development of Arsenic products are indicated. Furthermore, it points out promising directions for the treatment of As -containing materials. With the development of nonferrous metallurgy industry, new technology should be developed to reduce the production of harmful substance and the consumption of energy. Besides, we should learn excellent production experience from other countries, and try to make use of the secondary resources.
