Wikizero - Comminution

The most common machines for the comminution of coarse feed material (primary crushers) are the jaw crusher (1m > P 80 > 100 mm), cone crusher (P 80 > 20 mm) and hammer crusher. Primary crusher product in intermediate feed particle size ranges (100mm > P80 > 20mm) can be ground in autogenous (AG) or semi-autogenous (SAG) mills depending on feed

Comminution - Infogalactic: the planetary knowledge core

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with

Panning | mining | Britannica

Panning, in mining, simple method of separating particles of greater specific gravity (especially gold) from soil or gravels by washing in a pan with water. Panning is one of the principal techniques of the individual prospector for recovering gold and diamonds in placer (alluvial) deposits.

Clean artisanal gold mining: a utopian approach

3/1/2003 · Comminution involves the crushing and grinding of ore to reduce particles to a size suitable to liberate gold from gangue minerals through further processing (e.g. gravity concentration). Crushing and grinding are relatively simple mechanical processes, but are the most expensive unit operations in mineral processing.
