Copper extraction - Wikipedia

Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales, and the dense metal particles do not react with froth flotation media. Typically, if native copper is a minor part of a supergene profile it will not be recovered and will report to the tailings.

Pure copper metal is mostly produced from these ores by concentration, smelting, and refining. About 80% of the world's copper-from-ore is produced by concentration/smelting/ refining of sulfide ores. The other 20% is produced by heap leaching/solvent extraction/electrowinning of oxide, and chalcocite ores.

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.
