copper mining and leaching

Minerals Free Full

Copper is considered the third most important metal for industry after iron and aluminum with a yearly production of 10 Mt In the north of Chile there are many mining industries that produce copper in cathodes from oxidized minerals with the traditional process of leaching followed by solvent extraction SX and electrowinning LIX-SX-EW...
