ABSTRACT

Perspective conception is characterized by including of wastes assembly problems in
sphere of general actions for environment protection taking into account as any nonvalorized
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.
