what ores of pure metal use sulfuric acid in the process

to start “ore of pure metal” is a bit contradictory. ore as a term implies that the substance is a metal-containing compound which is why ores need to be either thermally or chemically (or both) processed in order to extract the metal. for examp

copper mining and extraction sulfide ores

about 200 years ago the uk was an important world source of copper and tin and there were mines in cornwall and devon. these mines have now closed and today the biggest copper mines are in chile (escondida mine) and indonesia (grasberg mine). these produce many millions of tonnes of copper ore per year. the main ores of copper are sulfides and

copper recovery using leach/solvent extraction

ranchers’ bluebird sulphuric acid leach/solvent extraction/electrowinning plant ranchers leached run of mine copper oxide ore (> 0.5% cu) placed in a sealed canyon in 20-foot layers (heaps) by distributing dilute sulphuric acid over the fresh ore via spray emitted from needle valves with pipes and needle valves

leaching of a cu-co ore from congo using sulphuric acidhydrogen peroxide leachants

a cu-co ore from katinga province the republic of congo containing 1.5% co and 1.6% cu was tested to determine the leachability of cu and co using sulphuric acid and hydrogen peroxide mixtures at different conditions. without hydrogen peroxide the maximum extraction of copper and cobalt were found to be ~80% and ~15% respectively when the acid

copper mining and extraction: oxide ores

most of the copper ores mined today are oxide or sulfide ores. extraction of sulfide ores is covered in more detail in copper mining and extraction: sulfide ores (11–14) but is introduced here because an important by-product of this process is used for the extraction of oxide ores. pyroprocessing sulfide ores provides acid for leaching
