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.

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.
