MATHEMATICAL MODELS OF PARTICLE SIZE DISTRIBUTION

ticle size during the comminution process (size reduction), plays a key role in the as sessment of process energy consumption and susceptibility of the ore to downstream upgrading processes. Particle size distributions are also significant in heuristic model ing of various enrichment processes (Tumidajski and Saramak 2010).

Introduction to Mineral Processing cpchem

Introduction to Mineral Processing. The process of froth flotation entails crushing and grinding the ore to a fine size. This fine grinding separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurry called the pulp.

Particle Size Analysis for Mining and Minerals

Extracting useful minerals is an arduous and technically demanding process. First, any material on top of the deposit, known as overburden, must be removed or tunneled through. In the next step, the ore is blasted or cut and loaded and hauled to the mill for the secondary crushing and grinding which prepares the material for its intended use.

Mineral processing

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
