Solid Ratio

In this paper, sulfuric acid leaching of copper slag at atmospheric pressure was used to produce copper sulfate solution and higher leaching ratio of copper sulfate solution was obtained. Meanwhile, some factors (Acid concentration, the temperature, the liquid-solid ratio, time and other) were investigated and analyzed in the production process. In addition, this work provided smelting plants with economically viable technology of copper recovery process from copper slag.

In this paper, nickel-containing residue, a typical solid waste produced in the battery production process, was used to study the cavitation characteristics of ultrasonic waves in a liquid–solid reaction. The ultrasonically-enhanced leaching technology for multicomponent and complex nickel-containing residue was studied through systematic ultrasonic-conventional comparative experiments. An ultrasonic leaching kinetics model was established which provided reliable technological guidance and basic theory for the comprehensive utilization of nickel-containing residue. In the study, it was found that ultrasonically-enhanced leaching for 40 min obtained the same result as conventional leaching for 80 min, and the Ni extraction degree reached more than 95%. According to the kinetic fitting of the leaching process, it was found that the sulfuric acid leaching process belonged to the diffusion-controlled model of solid product layers under conventional and ultrasonic conditions, and the activation energy of the reaction was Ea1 = 17.74 kJ/mol and Ea2 = 5.04 kJ/mol, respectively.
