As an example, it took approximately 150 hours to remove 90 per cent of the water-soluble copper by vat washing from the minus 1 plus ¾ inch size of a porphyry ore saturated with copper sulphate, where as only 31½-hours was required by alternate wetting and drying when the period of drying was 4.0 hours and the period of washing 0.5 hour.

Chile Copper Mines Energy Use and Solar Energy Potential. Chile is the highest copper-producing country in the world. The Atacama Desert in Northern Chile also receives the most solar radiation in the world, so is ideal for solar farm projects. Copper mining is energy-intensive. Crushing and grinding processes produce the most carbon emissions.

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 the ore into fractions.
