Gangue - Wikipedia

OverviewRe-useSee also

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 tailings, which is rock already stripped of valuable minerals; a worthless rock containing valuable material. The separation of mineral from gangue is known as mineral processing, mineral dressing, or ore dressi

Iron processing - Ores Britannica

Iron processing - Iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is ...

Mineral processing - Wikipedia

OverviewUnit operationsHistoryOther processesSee alsoConferencesNotesSources

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering– solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considere

Gangue Rejection Gekko - Mineral Processing Solutions

Gangue rejection is the process of separating and disposing the poorest, low-quality, low-value material in an ore feed prior to further downstream processing. Simply put, the focus is on the waste to reject, rather than the mineral to recover. Economic benefits are gained when the gangue volume is replaced with useful material of a higher grade.

Importance of mineral processing - MINERALLURGy

Processing the raw material without beneficiation of the ore will need a large number of chemicals and large size equipment, which is technically challenging. Mineral processing reduces the amount of gangue material and allows us to conduct metallurgy extraction processes.

What is liberation in mineral processing - MINERALLURGy

In mineral processing, we attempt to reach a mesh of practical release for which 80% of the fragments are composed of over 90% of useful minerals or gangue. For finely disseminated minerals, the primary role of the preparation process is the release of minerals because, without it, separation and beneficiation would be impossible.

Mineralogy Flotation: Floatability VS Selectivity Test ...

Mineralogy is the driving force behind flotation performance. A flotation batch and rate test measures this as mass pull recovery and concentrate grade. The real data from a rate test can be processed to determine the flotation kinetics of metal, mineral and gangue. What we cover here is what are kinetics and what do they mean. Special attention is paid to the definition of floatable gangue ...
