Gangue chemistry

In mining, gangue is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. It is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed, and from … See more Gangue minerals, once separated by mineral dressing processes of (most of) the valuable ore minerals and dumped in mine tailings may be a significant environmental impact. In particular, oxidation of pyrite, a common gangue … See more Minerals that were once thought of as gangue, and were dumped, may later find a commercial use. When this happens, the old dumps are often reworked to extract the wanted mineral. … See more • Froth flotation – Process for selectively separating of hydrophobic materials from hydrophilic • Magnetic separation – Process of separating components of mixtures by using magnets • Vanning – Ore dressing in which ores are washed on a shovel See more WebThe Behavior of Gangue During the Flotation of a Sulfidic PGM-Bearing Ore in Response to Various Monovalent and Divalent Ions in Process Water Malibongwe Shadrach Manono *, Kirsten Claire Corin and Jennifer Gael Wiese Centre for Minerals Research, Department of Chemical Engineering, University of Cape Town, Cape Town, South Africa
