  • GOLD RECOVERY FROM COPPER GOLD GRAVITY

    2020-8-10 · Overall gold recovery is about 90 . The mill has a gravity recovery circuit comprising one 30 inch Knelson treating screened cyclone underflow. This produces a high grade gold concentrate containing 1 to 4 gold and 5 to 7 copper which is upgraded on a table with recoveries of about 70 . This gravity circuit recovers about 50 of gold in feed.

  • Is Your Cyclone Helping or Hurting Your Gravity Gold Recovery

    Then all you re up against is gold getting smeared onto grinding media mill liners hanging up in pump boxes but it s trapped there in the circuit. Now the paper says this effect is minor as more than 98 of GRG entering the mill remains gravity recoverable after grinding.
