“…In pyrometallurgy, roasting is widely applied as a pretreatment, for instance, to recover gold from refractory gold ores and concentrates [3], to oxidize pentlandite for nickel extraction [4] and to eliminate the sulfur content of sphalerite concentrate prior to zinc extraction [5]. In many hydrometallurgical processes, particularly in which bioleaching of chalcopyrite or oxidative leaching of bornite and covellite are not capable of leaching metals efficiently, roasting is a key pretreatment step for conversion of sulfides into oxides before acid or ammoniacal leaching can be carried out efficiently [6].…”

“…Roasting is a surface reaction that results in the formation of an oxide layer. This layer remains porous allowing oxygen to pass into the unreacted inner sulfide portion of the particle, while the resulting SO 2 gas is released [14]. The sulfuric gas then reacts with metal oxides and excess oxygen to form sulfates, making the sulfation roasting process an environmentally friendly technology.…”

This research investigates the extraction of copper from copper-containing leaching residue, which includes 33.45% of copper, 14.14% of iron, 23.87% of sulfur and trace amounts of silver and other elements. Roasting the copper-containing residue under air and oxygen flow convert sulfides into sulfate, followed by water and acid leaching to extract copper. The process parameters, including leaching temperature, sulfuric acid concentration, leaching time, solid-to liquid ratio, and agitation speed, were optimized for both water and acid leaching methods. Results showed that the maximum copper dissolution efficiency was 93.12% with water leaching, and 97.16% with acid leaching. Chemical analysis revealed that the water and acid leaching residue contained 48.13% and 31.64% of iron, respectively. This study provides valuable insights into the process optimization for copper extraction from copper-containing leaching residue, which can inform the development of more efficient and sustainable methods for metal recovery.
