Dec 10, 2017· Hence, optical sorting threshold determination becomes difficult with low contrast particles in cases where optical sorting is based on surface color differenc Many efforts have been made to determine the efficiency, performance, and accuracy of the sorting process in mining/mineral processing industry (Udoudo, 2010)
Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation ,
Mineral processing - Mineral processing - Concentration: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated These properties can be colour (optical sorting), density (gravity separation), magnetic .
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
In mineral processing: Optical separation This process is used for the concentration of particles that have sufficiently different colours (the best contrast being black and white) to be detected by the naked eye In addition, electro-optic detectors collect data on the responses of minerals when exposed to infrared,, Read More
