Ore processing Waihi Gold

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.

Crushing in Mineral Processing

In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface. Less abrasive and softer rocks or stones

PRE-CRUSHING OF SAG FEED: FRIEND OR FOE

of this calculation relates to the empirically known reduction of SAG energy by pre-crushing. SAG energy is reduced by 5% for each 25.4 mm reduction in the F 80 size as shown in Figure 2 below. This relationship was determined from benchmark studies involving pre-crushing of F 80 152.4 mm feed to ~101.6 mm, done during the

Gold processing 101 Mining Magazine

However, the SAG route is more power-intensive and, for very hard ores, comes with some process risk in predicting performance. More recently, a hybrid solution has become available in the form of high pressure grinding rolls (HPGRs), which can replace the third stage of crushing and also the SAG mill.
