The ore lumps from the mines have the lump size of 10 - 100 cm while the individual minerals have grain sizes below 0.1 mm. Hence, the first step in any ore dressing plant is to aim at liberation by size reduction or comminution. Comminution of any ore is carried out in several stages using different crushing equipments.

Chapter 2 - Ore Handling. Ore handling is a key function in mining and mineral processing, which may account for 30–60% of the total delivered price of raw materials. It covers the processes of transportation, storage, feeding, and washing of the ore en route to, or during, the various stages of treatment in the mill.

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.

separates the heavy mineral from the fine ore. For the most finely crushed ore, processing workers use a method called froth flotation. This method is chiefly used with galena because the mineral is finely dispersed through the rock containing it. Flotation is the usual mineral separation or concentration process of choice.
