12 3 2 Process Description2-4 Mining produces ores with less than 1 percent copper Concentration is accomplished at the mine sites by crushing grinding and flotation purification resulting in ore with 15 to 35 percent copper A continuous process called floatation which uses water various flotation chemicals and compressed air separates

Copper processing

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 amount of

Agglomeration technique improves heap leaching process

Heap leaching relies on a leaching agent moving through a bed of heaped ore to extract the metallic components: Crushed ore is stacked on a leaching pad and irrigated with the leaching agent The leaching agent chemically reacts with the metal in the ore to dissolve the copper into the solution as it percolates through the heap

Copper Mineral

Uses of Copper Native copper was probably one of the early metals worked by ancient people Nuggets of the metal could be found in streams in a few areas and its properties allowed it to be easily worked without a required processing step Today most copper is produced from sulfide ores Copper is an excellent conductor of electricity
