· By "closed circuit" crushing or grinding it is meant that the product from a crusher or grinder is fed to a screen. The material that has been reduced to sufficient fineness passes through the openings and the oversize is returned to the breaker for further reduction. Escape from the circuit can only be through the screen so this product, the undersize, is equal in .

concentration process should be conducted at as coarse a crush size as possible while minimizing losses of pay metals. Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 µm with high separation efficiency, depending on liberation characteristics of the value minerals. The DMS process .
· A briquette is a compressed block of coal dust or other biomass material such as charcoal, sawdust, or paper used for fuel and to begin a fire. The term derives from the French word briquette meaning brick. Briquetting is the procedure of creating briquettes.
· Grinding is a necessary operation for the preparation of finely powdered coal (<75 μm) in power plants . Particle size, in general, also has an influence on the setting time of cements, flow characteristics of granular materials, compacting and sintering behavior of metallurgical powders, masking power of paint pigment, and flotation of coal and minerals [ 6 ].
Crushing equipment generally has a speci c reduction ratio and this ultimately means each crushing stage has a size limitation in terms of the nal products. This suggests that the number of crushing stages can be reduced or increased depending on the feed size accepted by the primary grinding stage (Wills and NapierMunn, 2006). Smaller and ner
to crush and grind the rock to unlock, or liberate, valuable minerals so that they are partially or fully exposed. This process of size reduction is called comminution. The crushing and grinding process will produce a range of particles with varying degrees of liberation The comminution process actually begins during the mining stage through the use explosives, excavators or .
