WebN2 - This work aims to evaluate the effectiveness of ground granulated blast furnace slag (GGBS) in removing copper from aqueous solutions. Batch adsorption studies were done to optimize conditions for the removal of copper. Factors affecting adsorption such as pH, GGBS dosage, contact time, copper concentration and temperature were determined. WebJun 1, 2010 · The copper smelting process produces plenty of copper slag every year, which is a hazardous solid waste, but a secondary resource. In the present study, the extraction of copper, nickel, and cobalt … Expand

Web(i) The technique of zone refining is based on the principle that the impurities are more soluble in the molten state of metal than in the solid state. Silicon , boron gallium , indium etc. can purify by this process. (ii) Ores of copper contain iron oxide as an impurity. Silica reacts with iron oxide and forms iron silicate, which is removed as slag. FeO + SiO2 ------ … WebMay 28, 2024 · This value is important because copper extraction from converter slag still occurs, even without stirring the solution. This is mainly due to the leaching solution diffusing throughout the slag via microcracks (pores) . These microcracks are produced by the sudden cooling of the slags in the pyrometallurgical process, when water (at 293 K ... jobs that offer benefits for part time
