Crushing in Mineral Processing
In mineral processing or metallurgy, the first stage of comminution is crushing Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wearresistant plate/surfaceMineral 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 metallurgyThe primary operations are comminution and concentration, but there are other important operationsMineral processing | metallurgy | Britannica
(PDF) SIZE REDUCTION BY CRUSHING METHODS
Crushing is the largest process operation in minerals processing The goal is to pr oduce rock or (more seldom) mineral fractions to be u sed as rock fill or ballast material for concrete and a sphaltCrushing Crushing is often one of the first steps in the production of rock, coal and other minerals, as mined material can consist of boulders that are too big to fit through the processing plant The type of crusher required depends on the material being reducedCrushing | McLanahan
