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.

1. Differential flotation or partial differential flotation process. When the content of copper is much more than nickel in the ore, this process can be used to separate the copper as the single concentrate. The advantage of this process is that the copper concentrate with lower nickel content can be obtained directly. 2. Bulk flotation process.
