PROCESSING OF SOLID MINING WASTES - A SOLUTION IN FIGHT AGAINST ENVIRONMENT POLLUTION

Perspective conception is characterized by including of wastes assembly problems in sphere of general actions for environment protection taking into account as any non-valorized waste or least non-used, pollute the environment. Processing of solid minerals sterile and obtaining of sub-products which are economically usable has major importance, both from economical and ecological point of view, through environment protection. Researches had followed elaboration of ecological technologies of processing the waste as mineral sterile, in order to obtain recovered products. By superior using of mineral compounds resulted from waste as mineral sterile or decantation stock-piles, products with economic value may be obtained, such as Portland cement, bricks, bolts, concrete slabs, BCA and BCU, etc. These researches put the base of a new approach mode of mining residues problem. It was followed that experimental models carried out at laboratory scale to contain equipments and installations of concentration with a low degree of pollution. Products obtained from pond sterile are according to the requirements imposed by quality norms in force.
