Mineral processing | metallurgy | Britannica

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive primary operations are comminution and concentration, but there are other important operations

 · Quartz, carbonate, fluorite, adularia, and vanadian muscovite/roscoelite are the most common gangue minerals. Alkalic-type gold deposits form in a variety of geological settings including continent-arc collision zones and back-arc or post-subduction rifts that are invariably characterized by a transition from convergent to extensional or

Common gangue minerals in the quartz include ankerite, siderite, calcite, kaolinite and chlorite. Sulphide minerals, in order of decreasing abundance, include arsenopyrite, pyrite, galena, sphalerite, chalcopyrite, pyrrhotite and stibnite. Gold commonly occurs with galena and arsenopyrite,

Effect of Gangue Mineralogy on Flow Sheet Design and Plant

However, gangue minerals with layered silicate structures ( micas, chlorite, clay minerals) are universally problematic during materials handling due to their propensity to absorb water, easily slime during grinding/milling, depress physical-chemical-thermal separation of ore from gangue minerals, and finally inhibit separation of fluids from residues leading up to final disposal.

sorting ore ore and gangue ore

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 mineral, is one of the main sources of acid mine drainage.

Investigation of surface properties of gangue minerals in

floatable gangue minerals such as talc. Although talc is present in small quantities it has a disproportionate effect by enhancing froth stability and increasing the entrainment of other gangue minerals. However, there is an indication that some of the other gangue minerals, which are normally considered to be hydrophilic, such as chromite and pyroxene, report to the concentrate as floatable

Gangue minerals | SpringerLink

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 principal

Mine Waste Transfer and Disposal Methods - Mine Tailings

Gangue Gangue is the worthless rock or material that is closely mixed with the valuable material to be processed. The separation of minerals from gangue is called mineral processing. Oftentimes, inefficient processing methods can produce gangue that still holds an ample amount of valuable minerals.

Gangue - Wikipedia

Quartz is by far the most common iron ore gangue mineral overall, whereas clays (kaolinite and gibbsite) predominate in weathered supergene altered and near-surface exposures of ore deposits, while minnesotaite and stilpnomelane are the most common silicate minerals in unweathered iron formation deposits. There are many other major to minor gangue minerals associated with iron ore deposits

Gangue Minerals Effect -

Liberation of the valuable minerals from the gangue is accomplished by size reduction or comminution, which involves crushing and grinding to such a size that the product is a mixture of relatively clean particles of mineral and gangue, that is, the ore minerals are liberated or objective of comminution is liberation at the coarsest.
