Abstract:

In order to solve the problems of tailings dumps and drainage in Penglai Mining concentrator,by comparing of the advantages and disadvantages of various stacking methods,combined with the current concentrator process characteristics and geographical features,we successfully resolve the problems of tailings pile,backwater and flood during the rainy season by using the ways of dam -front pile up and ulverts drainage.The successful application of this tailings dumps and drainage way provides valuable experience about tailings maintenance and use for small valley-based concentrator,has good economic and social benefits.
