Tailings Problems and Tailings Utilization and Treatments in the Metal Mines

Cai Sijing,Yang Peng

Strategic Study of CAE 2000, Volume 2, Issue 4,   Pages 89-92

Abstract: Tailings dam occupies large area of land. Accidents may be caused by tailings dam failure.tailings, utilizing tailings to make building materials or magnetized fertilizer, etc.The treatment of tailings should include depositing tailings underground, utilizing tailings dam as awaste dump, and land reclaiming while depositing tailings paste.The final purpose of utilizing and treating tailings is to set up a “mine without tailings&rdquo
