Ore Treatment - an overview | ScienceDirect Topics

On-stream particle-size analysis. In mineral processing, an excessively large mean particle size results in inefficient extraction of the wanted materials whilst over-grinding is time-consuming and expensive. For efficient operation, therefore, ores should be ground to an optimum particle-size distribution, and hence there is a need for an ...

Mechanical screening - Wikipedia

Mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size.. This practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling.. A method of separating solid particles according to size alone is called screening.
