Two types of steelmaking slag were used in the experiments. Ca-slag has high pH and high calcium oxide content due to its short period of aging. In contrast, Fe-slag is oxidized for a …
Artisanal and Small-Scale Gold Mining Without Mercury
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 … 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 WebTailings are the waste materials left after the target mineral is extracted from ore.
