The slag with the size of 10 mm is not exposed to magnetic separation and conveyed into the sinter blend. Various studies related to utilizing the BOF slag through sinter making have been done and summarized the methods of slag making [16]. A sinter plant, which was
nonferrous metals (nickel and copper) versus iron, from nickel slag by selective reduction−magnetic separation process, with an aim to make highgrade nickel and copper concentrate for producing special steel, stainless steel or weathering steel [14,15]. 2 Experimental Raw materials The nickel slag, which was generated from a flash
Nov 14, 2013· A separation process for upgrading iron from waste copper slag was developed. • The process mainly includes reduction, crushing and magnetic separation steps. • The magnetic product obtained from the process contains over 65 wt.% iron. • The percentage recovery of .
Studies on the direct reduction of carbonbearing pellets made from discarded copper slag have been conducted in this paper. They include the influences of reduction coal content, limestone content, industrial sodium carbonate content, reduction temperature, reduction time and layers of carbonbearing pellets on reduction effect. Finally, the optimum conditions have been obtained.
Waste copper slag is a refractory material with high iron content, but it is difficult to recovery iron minerals from the slag because the iron mainly occurs in fayalite. A new technology of coalbased direct reductionmagnetic separation process was developed to recover iron from the slag assaying % Fe total and % Cu.
The recovery body of copper slag was mainly copper matte, returned to smelting process of copper by means containing acid leaching, flotation recovery and depletion recovery. 3,7,8) Copper slag contains large amounts of fayalite, direct magnetic separation of iron recovery is limited. Recycling method for Fe is mainly roastingmagnetic ...
