Sep 20 2017 · therefore, flotation and leaching, both of which are the first stage of each scenario, of finely-ground ores are of crucial importance to assure the continued supply of metals. this special issue will be devoted to collecting papers on recent advances in selective flotation and leaching processes for any metal-containing ores.
the pool leaching process is a common leaching method used in early wet copper smelting. using the strong sulfuric acid solution to leach the copper-contained oxidized ore because the concentration of copper in the leach solution is high, it can be directly used for the copper electrodeposition.

to the flotation mills or leaching plants except possibly for dust con trol in handling. metallurgical, methods nearly all low-grade copper sulfide ores and some native copper ores are reduced to copper in three separate steps. the ore is first concentrated by flotation, then reduced to
copper processing copper processing ores: principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. native copper is simply the metal found unadulterated in nature. occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.
the pregnant leach pond contains copper ions that give it the blue colour of copper sulfate. the liquid is continually pumped to the sx-ew plant. copper sulfate solution is collected in the pregnant leach pond then pumped to the solvent extraction plant. the solvent extraction phase of treatment occurs in
until recently, conventional acid-leaching of copper was utilized as a means of recovering copper from low-grade materials such as waste rock and flotation tailings and was conducted in dumps that were already in place. At least five factors have impeded the acceptance of leaching as a
