Embodiment 1
[0015] The alloy powder with the mass percentage composition of Cu 67.87%, Co 5.71% and Fe 23.46% is placed in the liquid after electroplating according to the liquid-solid ratio of 30:1 to carry out the iron-dissolving reaction. The reaction temperature is room temperature -60 ℃, and the obtained The copper powder, alloy and solution are put into the leaching kettle for oxidative leaching. The solution is added with sulfuric acid until the acid concentration is 0.5mol / l, the operating temperature is 370K, the reaction pressure is 0.6MPa, the reaction time is 3 hours, and the amount of additives added is 5g / l. L, the components of the obtained iron slag after filtration and drying are (mass percent) Cu 0.1, Co 0.08, and Fe 50.7. The composition of the leaching solution (g / L) Cu 44.83, Co 3.77, Fe 0.04, the leaching rate of copper is over 99%, and the leaching rate of cobalt is over 99.3%.
