CSIRO Team Leader, Dr David Miljak, said theoresorter is likely most suited to thecopper miningindustry as it can detect these minerals at extremely low grades. He believes the processing costs for a bigminingoperation will drop radically for each pound ofcopperor ounce ofgoldproduced – as much as 20% in some mines.
Although basic porphyrycopperflotation and metallurgy has remained virtually the same for many years, the processingequipmentas well as design of the mills has continually been improved to increase production while reducing operating and maintenance costs. Also, considerable attention is paid to automatic sensing devices and automatic controls in order to assure maximum metallurgy and ...
