Kinetics of copper extraction from copper smelting slag by

15-06-2020· When the temperature is 200 , the leaching rate of copper and iron can reach 97.2% and 0.58% respectively. This is because that the increasing of temperature enhances the behavior of iron conversion that FeSO 4 produced by reaction is oxidized to Fe 2 (SO 4) 3 which is subjected to hydrolysis then form hematite (Fe 2 O 3) and release sulfuric acid .

Minerals | Free Full-Text | Leaching of Primary Copper

Copper extraction from primary copper sulfide ore from a typical porphyry copper deposit from Antofagasta, Chile, was investigated after leaching with a chloride-ferrous media at two temperatures. The study focused on whether this chemical leaching system could be applied at an industrial scale. Leaching tests were conducted in columns loaded with approximately 50 kg of agglomerated ore; the

Leaching Behaviour of Metals from a Sphalerite

Leaching behaviors of zinc, copper, indium and iron from a sphalerite concentrate in sulfuric acid-oxygen system has been investigated in the present paper. Various parameters were studied including particle size, concentration of sulfuric acid, partial pressure of oxygen, leaching temperature, and leaching time. The experimental data indicated that under the typical plant conditions employed
