Mineral processing metallurgy Britannica

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.The primary operations are comminution and concentration, but there are other important operations ...

Ore Dilution amp Recovery in Mining

Apr 05, 2017 Ore Dilution & Recovery in Mining. Recovery and dilution usually are interrelated; with some methods of stoping a high recovery involves contamination of the ore from the walls or capping, and often clean ore can be obtained only by leaving some ore in the mine. In open-stope mines the greatest loss of ore is that tied up in pillars left for ...

Ore Mining and Dressing Preliminary Study Report 2011

Mining, Dressing (Beneficiation), and Mineral Processing Ore mining consists of three major types of operations: mining, dressing, and mineral processing. 40 CFR Part 440 pertains to wastewater from mining and dressing activities, but not from mineral processing, which is …

Mineral dressing = Orebeneficiation

operations by which the lump size is reduced step by step. There are 3 stages of crushing and 2 stages of grinding. – i. Primary Crushing (coarse crushing): In primary crushing, ore or run-of-mine ore (up to 1 m in size) is crushed down to about 10 cm and it is done in a jaw or gyratory crusher. – ii.


The crude ore from the mines contain a number of solid phases in the form of an aggregate. The valuable portion of the ore is known as mineral while the worthless portion is known as gangue. During ore dressing, the crude ore is reduced in size to a point where each mineral grain becomes essentially free so as to make separation between them.
