• 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.

mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.

MINERAL PROCESSING MILLING Introduction Milling, sometimes also known as fine grinding, pulverising or comminution, is the process of reducing materials to a powder of fine or very fine size. It is distinct from crushing or granulation, which involves size reduction to a rock, pebble or grain size. Milling is used to produce a variety

Mineral Processing. Mineral processing is the process in which chemical or physical methods are used to separate the useful minerals in the ore from the useless minerals (usually called gangue) or hazardous minerals, or to separate multiple useful minerals. In the early years, mineral processing was called mineral concentration or mineral ...

Crushing, a form of comminution, one of the unit operations of mineral processing. In the field of extractive metallurgy, mineral processing is the process of separating commercially valuable minerals from their ores. [1] Depending on the processes used in each instance, it is often also known as ore dressing or ore milling .
