Particle Size. The particle size to which the ore is ground depends on the nature of the ore. The grind must be fine enough to liberate the mineral grain from associated rock, but producing too small a particle size is both expensive and detrimental to recovery. Froth flotation is generally limited to size fractions between roughly 65 and 100 mesh.

The proper size range for separating the metal from the waste ore varies depending on the type of metal mined. For example, a typical copper concentrator will attempt to grind ore to between 400 and 35 mesh (74 and 210 microns.) Ore in this size range will successfully separate the copper from the tailings in the downstream in the flotation cells.

Particle Analysis in Mining and Minerals HORIBA

In many cases, the valuable minerals are mixed with gangue, commercially useless material, and the ore must be separated. 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.

Crushing in Mineral Processing

2020-6-25  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. Less abrasive and softer rocks or stones
