Mineral dressing (= Orebeneficiation)
• The process of froth flotation involves crushing and grinding the ore to a fine size – This separates the individual mineral particles from the waste rock and other mineral particles. – The grinding is normally done in water with the resultant slurrycalled the pulp. • The pulp is processed in the flotation cells.

What is the purpose of crushing, grinding and milling operations in
Answer: The purpose is to break the valuable mineral grains free of the gangue minerals, so that they can be physically separated from each other. This makes it possible to produce a pure mineral concentrate using processes like froth flotation or magnetic separation.

Crushing Mineral Processing
In mineral processing, the reduction of minerals by crushing and grinding may be regarded as having one or other of two main objectives: the attainment of a size appropriate for the direct industrial application of the mineral, e.g. barytes, sand, aggregate; or the release of metallic or ore inclusions from an unwanted matrix with a view to maximum separation.
