The first step of many separation processes is comminution (size reduction) followed by classification (separation by particle size) either for further grinding or the next step, concentration of the ore. During comminution, ore must be ground such that the particles are small enough that each particle consists of primarily one mineral.

Mar 20, 2016 The simplest case may be represented by a low grade copper ore which in its natural state could not be economically shipped or smelted. The treatment of such an ore by flotation or some other process of concentration has this purpose: to concentrate the copper into as small a bulk as possible without losing too much of the copper in doing so.

From the profile in figure 4.2, it can be concluded that the particles in the haematite ore re- ceived from the lab have a wide particle size distribution. In other words, ore material consists of large particles and fines. The particle size is not uniform. This profile may be indicative of the type of process used to crush the feed material.

W is the work (energy) input per ton. F80 is the 80% passing size of the circuit feed, and P80 is the 80% passing size of the circuit product, in microns. For example, a grinding circuit is processing 450 t/h (of dry feed) with a mill drawing 3,150 kW (at the pinion).

Roasting (metallurgy)

Roasting is a process of heating a sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.
