most copper ores contain only a small percentage of copper. the remainder of the ore consists of gangue of no commercial value. gangue from copper mining typically contains silicate mineralsand oxides. in some cases these tailings have been retreated as the technology for recovering copper has improved. the average grade of copper ores in the st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. a key · text under ccbysa licenseautoclave leaching of copper nickel mattemay , · the copper extraction at 100 rpm was only 24 pct. previous investigators have reported that the copper extraction is enhanced by the presence of ferric ion. therefore, agitator speed of over 100 rpm are required to oxidize the ferrous ion to the ferric state and the latter appears to enhance the copper extraction. effect of airflow
