PREPARATION METALLURGICAL SLAG FOR RECYCLING

Gagarina T.B, Ksandrov N.V, Kim P.P, Peretrutov A.A
Dynamic method with different concentrations of ammonia from 5% by weight. up to 25% wt., ammonium chloride 50-180 g / l, a different ratio of T: L 1:10-1:15 and time of the leaching process 0.5-4 hours to determine the maximum conditions of extraction of non-ferrous metals, zinc. The accuracy of the results when tested copper smelting slag, he in turn is a waste of metallurgical production. The results are a convergence systematic error does not exceed 0.15%. The optimum concentration of the leaching solution are found, graphical differentiation of the kinetic curves determined the rate constant for recovery of zinc from the slag. The increase in the degree of extraction of zinc compounds with increasing concentrations of ammonia. The slag after the leaching can be used for reception the lead, and iron can be used in the construction industry.
