Leaching Medium-High Grade Copper/Silver Ore ...

you'll need to acid leach the oxide copper 1st. Then you neutralize and cyanide leach the silver. I think a better option is it hydroxamate float the Cu oxide and Ag together and sell that to the smelter. If the smelter does not want it, you can acid leach the flotation concentrate, neutralize, and NaCN leach the silver. Much smaller mass/cost.

Leaching of malachite using 5-sulfosalicylic acid ...

5-SSA is used to leach copper from malachite for the first time. • 5-SSA can generate ionization and complexation reaction with copper ions. • 5-SSA can be used to process copper oxide ores. • The leaching rate of copper is higher than 99% under the optimum leaching conditions. •

Investigation of selective leaching and kinetics of copper ...

The results obtained shown that copper in the ore matrix was completely leached while zinc and iron were partially dissolved in perchloric acid solutions. In addition, the effects of the acid concentration, reaction temperature, stirring speed, particle size, and solid-to-liquid ratio on the leaching of malachite were researched.
