Ore processing Waihi Gold

2021-11-12  Ore is stockpiled (1) 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 (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.

What's the Difference Between SAG Mill and Ball Mill

2019-11-26  The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill’s

Gold. Gold reserves at the beginning of 1988 was estimated at 101.6 million metric tons (MT), equivalent to about 240 MT of gold metal. Between 1988 and 1994, a total of 27.7 million MT of gold ore, containing about 36 MT of metal was extracted. On the average, this is equivalent to an annual extraction of 3.9 million MT of gold ore.
