- The acid leaching kinetics of serpentine was researched.
- The results proved that the temperature of acid leach is main factor affecting yield.
- The valuable metals such as antimony and lead from the acidic leaching residues were recoveried by vacuum carbothermal reduction.
- The effect of pre-treatment of the asbestos tailings on the acid leaching reaction of asbestos tailings was studied.
- Remove of iron from sulfuric acid leaching solution of ferrochromium alloy by goethite is researched.
