In mining, gangue (/ ɡ #230; ŋ /) 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 tailings, which is rock already stripped of valuable minerals.
Automated Hyperspectral Logging. The successful development of iron ore resources is fundamentally linked to our ability to accurately identify not only multiple species of iron oxide minerals, but also sub species, phases (eg. ochreous vs. hard) and associated gangue minerologies.
Lower grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high quality fine ore powders, are known as fines.. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals
Magnetite (Fe 3 O 4) is a common iron ore mineral in iron ore deposits of metasedimentary and magmatic origin.Magnetite has an inverse spinel structure and is partly altered in near surface environments to hematite or kenomagnetite (Waychunas, 1991).Hematite is commonly thought to form from oxidation of magnetite in the near

Gangue is valueless mineral associated with a valuable mineral that can economically be utilized, which is an ore .e.g. pyrite (FeS2) will be a gangue mineral associated with say sphalerite (ZnS) if the latter mineral can be utilized commercially; likewise, quartz/calcite will be gangue minerals associated with say an ore of copper

Tailings are a fine grained residue, mainly consisting of gangue minerals that remain after the separation of valuable minerals and metals from their ore in a processing facility. Tailings are deposited in the vicinity of the mine and are therefore pumped together with process water to large ponds, known as tailings impoundments, where the
