gold ore beneficiation process

  • PHASES OF A MINING PROJECT

    The gold content of a good grade gold ore may be only a few onehundredths 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 nonmetallic material of the ore in a process called 'beneficiation.' Milling is one of the most costly parts of beneficiation, and results in very fine .
