CHAPTER 01 Metal Recovery INTRODUCTION The flash smelting process has been used in copper industry for a number of years and has replaced some conventional copper smelting processes in Chile. The high copper content in the slag in this process, requireMetal Recovery from Steelmaking Slag,Metal Recovery from Steelmaking Slag Qi Yu Master of Applied Science Materials Science and Engineering University of Toronto 2018 Abstract An experimental study was carried out to recover metal values from a steelmaking slag through air oxidation and magnetic separation. The oxidation of slag was carried out in both solid and liquid states, attempting to optimize the conditions of each. The,Recovery of iron and removal of hazardous elements from,,2016-11-20· Iron recovery from molten copper slag via the carbothermic smelting reduction process was increased upon the addition of up to 20 wt% CaO; this improvement was caused by the increased fluidity of the slag. However, the addition of 30 wt% CaO decreased the iron recovery; this was caused by the precipitation of solid compounds (e.g., dicalcium silicate). Because the reduction degree of FeO
