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.

In-pit crushing conveying & ore sorting

A typical gold mine operation consumes 25-150kWh of electricity per tonne of processed ore (Calvo, Mudd, Valero and Valero, 2016). This means that if mill feed tonnes can be cut via bulk ore sorting ahead of the processing phases, a mine can significantly decrease energy, water and reagent consumption – as well as tailings.

Ore processing – Waihi Gold

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. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself.
