Adsorbents based on magnesium-ferrous slags of the nonferrous metallurgy for cleaning technological waste water from non-ferrous metals' cations....

The way of sorption clearing of large-capacity waste water of the nonferrous metallurgy enterprises from cations of Ni, Co, Cu has been proposed. A low-cost effective sorbent on the basis of a hardening mineral dispersion technology using the slag formed as a result of ore-thermal processing of sulphiric copper-nickel ores has been developed. The optimum conditions of synthesis have been revealed; the phase structure of reaction products and the sorption mechanism have been defined. The method of recycling of waste sorbents containing up to 5.0-5.5 weights % of nonferrous metals (Ni, Co, Cu) has been proposed. These waste sorbents can be used as raw material in ore-thermal furnaces. The degree of nickel extraction is 99.9 %.
