Copper Flotation And Leaching

345 pt and 71 pd the best leaching results of 48 pt and 245 pd were obtained using aqua regia solution though it is nonselective leaching of rom ore is generally not preferable as it leads to high reagent consumptions in this study it was postulated that leaching of low grade flotation concentrate would be preferred.
