A Comparison on Tailings Treatment and Disposal of Aba Lead-Zinc Concentrator

Abstract:

Tailings from Aba zinc-lead concentrator cannot be discharged in tailings dam by traditional wet disposal method due to the location restriction and environmental consideration. Treatment and disposal of the tailings become a serious problem that should be solved. Through investigation of tailings disposal in similar concentrators of China, a joint process of dewatering by hydrocyclones and pressure filters has put forward, in which a dry material can be obtained and disposed in dry manner, and the water produced in the process can be reused. This process is expected to set a good example for concentrators where construction of tailings dam is impossible
