The purpose of this research is to provide a new insight into leaching behavior of the materials of before and after SOR, to reveal the mechanism of enhanced V leaching efficiency. The effect of leaching parameters on leaching rate, phase transformation, micromorphology evolution, and kinetic of different samples were discussed.
Process Of Leaching Gold. A process of leaching gold comprising the steps of: a) leaching copper from copper sulfide ore material that contains gold or contains silicate ore containing gold until the copper grade is reduced to 7.9 wt % or less; b) mixing the resulting material having a copper grade of 7.9 wt % or less with a gold leaching solution …
