The trend of declining copper head grades is well established and unlikely to be reversed Similarly, oxide ore bodies, which do not require concentrators and can copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products samovar In its pure form or as an alloy, copper (Cu) is one of Copper processing Definition, History, & Facts Britannica
The average grade of copper ores in the 21st century is below 06% copper, with a proportion of economic ore minerals being less than 2% of the total volume of the ore rock Thus, all mining operations, the ore must usually be beneficiated (concentrated) The concentrate is typically sold to distant smelters, although some large mines have smelters located nearby Such colocation of The Copper Mining Process Once it’s located within the earth, copper ore goes through eight stages before the consumer sees it in various products that affect every day life in Copper Mining and Processing: Everything you Need to

Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries Copper is typically extracted from oxide and sulfide ores that contain between 05 and 20% copperAfter mining, copper is produced by one of two process routes: pyrometallurgical or hydrometallurgical Within the pyrometallurgical route, the mined ore is crushed and milled, followed by a concentration step using flotation The obtained copper concentrates contain on average 30 percent copper, but grades can range from 20 40 percent (ICSGCopper Environmental Profile Copper Alliance

With the gradual decrease in the grade of copper ores being processed, copper concentrates have become more complex with higher impurity and gangue content This trend has had a detrimental effect on smelters as they have to increase throughput to maintain copper metal production, while increasing operating costs due to processing The trend of declining copper head grades is well established and unlikely to be reversed Similarly, oxide ore bodies, which do not require concentrators and can be processed through less capitalintensive routes, are being exhausted The mining industry has responded to these challenges by processing everincreasing volumes of sulfide oresCopperprocessing technologies: Growing global copper supply
