Institute, Kunming 650031, China摘 要:In this paper, the kinetics of pressure leaching for purification of metallurgical grade silicon with hydrochloric acid was investigated. The effects of particle size, temperature, total pressure, and concentration of hydrochloric acid on the kinetics and mechanism of iron removal were studied. It was found......

completely[1]. During bioleaching and acid leaching processes, pyrite is expected to be oxidized as fast as possible to increase the leaching velocity[2]. In flotation... on[4-6]. Reports on influencing factors in bioleaching of pyrite are available[7-8], but there are few reports on germ-free acid leaching. Therefore, in this study, the influencing factors of pyrite......

Abstract: A kinetic study on the sulfuric acid leaching of multi-metal oxide, which is the product of multi-metal copper alloy with iron trioxide roasted in oxygen, was carried out. The effects of leaching time, stirring speed, sulfuric acid concentration, reaction temperature, and particle size of the multi-metal oxide on the kinetics and mechanism of copper extraction were studied. It was found......
