CHAPTER I National Metallurgical Laboratory

Mineral processing involves a number of unit operations starting with the run of mine (ROM) ore as the initial raw material. Traditionally the scope of mineral processing is limited to liberation of individual mineral phases and their separation from each other without altering the identity of any mineral …

Electrostatic Separation SER | Physical Chemistry ...

ELECTROSTATIC HIGH TENSION SEPARATION Principle This separation technique uses the differences in electrical conductivity between various minerals. Suitable for mineral particles in the size range of 75 to 1000 microns. <10 micron cannot be used. Universal concentrating method Best result with very dry material. (Heating is imp) Industrial application: Limited application,

Mineral processing | metallurgy |

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.
