Recomendation on gold ore processing technology

WHAT’S HAPPENING IN GOLD ORE PROCESSING? April 2019 . Factors driving new developments in gold technology include increasing environmental concern and government regulation over the use of cyanide, the trend towards refractory, complex, and lower grade resources, and the pressure to reduce operating cost and increase plant performance efficiency

    Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for

    one percent. The gold content of a good grade gold ore may be only a few one-hundredths of a percent. Therefore, the next step in mining is grinding (or milling) the ore and separating the relatively small quantities of metal from the non-metallic material of the ore in a process called ‘beneficiation.’ Milling is one of the most costly
