Silicification of Hydrothermal Gangue Minerals in Pb

Conversely analogous late-stage calcite and fluorite assemblages are only rarely observed In summary silicification is a typical cooling effect in various hydrothermal vein-type deposits but affects different gangue minerals in different ways depending on their temperature-dependent solubility Get price


Mineralogical control of minerals processing circuit design

minerals are overground The objective of some milling circuits is thus to put sufficient milling energy into the primary milling stage to liberate the sulphide minerals from the main gangue minerals but not an excess that may lead to a reduction in the amount of pgm values that are recovered through attachment to a major sulphide mineral Get price


importance of gangue

As generally used gangue minerals have no commercial importance in a particular period of time possibly becoming ore minerals at a later date They are commonly silicates carbonates or fluorides more rarely sulfides The gangue minerals of ore deposits formed at high temperatures differ from those deposited at lower temperatures The Get price
