  Ore Processing | OceanaGold - Waihi Operation

  202473 · Ore processing is a 24 hour operation. Ore is stockpiled at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added to raise its pH. Following crushing through a jaw crusher, the ore is fed into the semi autogenous grinding (SAG) mill along with water and steel balls.

  Ball Grinding Process | SpringerLink

  2023727 · Ball grinding process is a grinding method of crushing ore with ball-shaped grinding medium in the grinding mill. In the ball grinding process, because the steel ball has 360° free rotation, it is suitable for falling motion and throwing motion. When the rotating speed of the cylinder is low, the medium rises to a certain height along the ...
