The copper mining process. KAZ Minerals operates six producing mines. The three mines in East Region are underground while the Bozshakol, Aktogay and Bozymchak mines are open pit. The mines generally contain sulphide ores and by-products that vary in quantities and proportions between mines. The main by-products are zinc, silver, gold and ...
Apr 27, 2016 The lead and copper must be removed in bulk as a mixed concentrate and then the zinc floated as a separate concentrate because of marketing requirements. A further separation of the lead-copper into their respective products by flotation is often economically advantageous if the crude ore contains 0.8 copper 16 pounds per ton or more.
