2020· Ammonia leaching of slag from direct-to-blister copper smelting technology. Smelting of copper concentrates in a flash furnace directly into a copper blister results in the production of slag with high copper and lead content. The recovery of these metals is carried out in an electric furnace Fecobalt recovery from direct to blister slag,

U Ge reasonable solutions for any size-reduction requirements including silver obtained from the slag produced by copper smelting such as in the fusion and conversion of slag a computational thermodynamic model of direct to blister copper smelting is described and then used to examine the differences between the smelting of a high iron chalcopyrite concentrate and a low iron bornite concentrate. The rapid decrease in copper recovery as the iron content of the concentrates increases is clearly seen.The complex nature of some of the Direct-to-Blister slags makes it very difficult to present the slag com- positions and the thermodynamic behavior of the slags in simple diagrams. The ternary phase diagram SiO 2 - CaO-Fe2O3 gives some indication of the liquidus temperatures and the components,
