with copper). "Copper is increasingly recovered by solution methods, including dump and in situ leaching. Because most copper ores are insoluble in water, chemical reactions are required to convert copper into a watersoluble form; copper is recovered from a leaching solution through precipitation or by solvent extraction/ electrowinning (SX/EW).

Copper facts
Copper is one of the few materials that does not degrade or lose its chemical and physical properties during the recycling process. Recycling has the potential to extend the use of resources and minimize waste. The International Copper Study Group estimated that 33% of the world's copper consumption came from recycled copper in 2017.
