Concentration of the Ore When an ore has a low percentage of the desired metal a method of physical concentration must be used before the extraction process begins In one such method the ore is crushed and placed in a machine where by shaking the heavier particles containing the metal are separated from the lighter rock particles by gravity
The recovery of metals from sulfiderich ore bodies proceeds through a series of steps from mining to crushing to mineral recovery ie concentration followed typically by smelting of the sulfide concentrates and thence to metal refining although the nature of the ore body dictates the processes used to extract metals from ores each of
Process steps include mining concentration roasting smelting converting and finally fire and electrolytic refining 1232 Process Description24 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
Copper ore typically contains only about 06 of the actual copper mineral the most common ore mined being chalcopyrite The ore is attained using traditional methods of underground and open pit mining the later accounting for 90 of the ore used in smelting
The beneficiation process generates highvolume waste called tailings the residue of an ore that remains after it has been milled and the desired metals have been extracted eg with cyanide gold or sulfuric acid copper If a mining project involves the extraction of a few hundred million metric tons of mineral ore then

The use of highpressure rolls in the mining industry has been slow however because of the high capital cost of the units and because the process has to be dry Nevertheless it is evident that mineral liberation could be improved with these devices and with more experience and research this technology is expected to gain greater acceptance
The barren rock or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore By far the greatest proportion of copper is extracted from the sulfides of copper iron and sometimes other metals Such ores originate from sulfurbearing volcanic magmas which have separated into metal sulfides and siliceous melts

Concentrating The ore is enriched using a process called froth flotation Unwanted material called gangue sinks to the bottom and is removed Roasting This is where the chemical reactions start The powdered enriched ore is heated in air between 500176C and 700176C to remove some sulphur and dry the ore which is still a solid called calcine

The ore extraction process known as mining can take on various forms depending on the type of ore involved and takes place on every continent on Earth except for Antarctica
Recovery and dilution usually are interrelated with some methods of stoping a high recovery involves contamination of the ore from the walls or capping and often clean ore can be obtained only by leaving some ore in the mine In openstope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall The amount of ore thus left varies considerably
As a rule of thumb open pit mining can process ore for 10 per tonne and where the ore grade is more than double that at 20 per tonne results would be economic Consider that 1 of a metric
