  • Mineral Processing Part 2 Geology for Investors

    Nov 19, 2020· Optical Separation is the separation of minerals by color. Optical sorters expose the ore material to infrared, visible, and ultraviolet light. A sensor detects how the light is reflected or absorbed by the different minerals in the ore material. Mineral processing is a crucial part of a comprehensive investment decision, even though it

  • Separation in mineral processing Minerallurgy

    Nov 18, 2019· Separation in mineral processing refers to the separation between valuable minerals and gangue, and also valuable minerals between each other.

  • 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

  • Mineral processing Dewatering Britannica

    Mineral processing Mineral processing Dewatering: Concentrates and tailings produced by the methods outlined above must be dewatered in order to convert the pulps to a transportable state. In addition, the water can be recycled into the existing water circuits of the processing plant, greatly reducing the demand for expensive fresh water. Filtration is the separation of a suspension into a
