    Mineral processing,  · Urban mining is the process of recovering these rare metals through mechanical and chemical treatments. The name was coined in the 1980s by Professor Hideo Nanjyo of the Research Institute of Mineral Dressing and Metallurgy at Tohoku University and the idea has gained significant traction in Japan (and in other parts of Asia) in the 21st century.flotation process in mineral processing, 2020-10-11 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 operationsSlurry pipeline,  · In the field of extractive metallurgy, mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores. Various theories of ore genesis explain how the various types of mineral deposits form within the Earth's crust.
