SGS Minerals Services metallurgical group has developed new flotation reagents that yield excellent primary separations between Ta and Nb minerals and gangue. The sample to the right is a highly liberated Ta Nb ore pyrochlore, columbite bright white with a calcite quartz gangue dull grey, which responded well to these reagents.
Copper Fe sulfide ore deposits typically have Cu grades varying from 0.5 to 5 . This equates to approximately 1.5 to 15 sulfide minerals, hence 85 to 98.5 of the remaining ore massprised of gangue minerals. Many of the gangue minerals are relatively benign during mineral processing and subsequent hydrometallurgical and/or pyrometallurgical processing.

Discovered in 1988 owned by Lynas Corp. Rare earths are contained in secondary phosphates and aluminophosphates, presumably derived from weathering of the Proterozoic Mount Weld
Geochemically, the Bayan Obo ore deposit was enriched by ore metals in the sequence REE's, Fe, and Nb and the gangue elements P, F, and Ba. Bayan Obo is characterized by the scarcity or lack of U, S, Ta, Al, the precious metals Au and Ag, and base metals Cu, Pb, and Zn. MINERAL ASSEMBLAGES AND THE TRANSPORT OF REE'S IN HYDROTHERMAL FLUIDS
The second stage consists of quartz, dolomite, ankerite, siderite, chalcopyrite, sphalerite, pyrite, galena, selenian galena, marcasite, nevskite, and paraguanajuatite. The gangue minerals are dominated by quartz and various carbonates, locally associated with chlorite.

Quartz is by far themon 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 themon silicate minerals in unweathered iron formation deposits.
Coarse comminution test work and modeling are powerful tools in the design and optimization of mineral processing plants and provide information on energy consumption. Additional information on mineral liberation characteristics can be used for assessing the potential of pre concentration stages or screens in the plant design. In ores of high value metals e.g., Ta, W, standard
Common gangue minerals include quartz, biotite, muscovite, K feldspar, albite, chlorite, and scapolite many deposits contain minor to major amounts of tourmaline. Altered wall rocks generally have abundant biotite or albite. Mesoproterozoic metasedimentary successions constitute the predominant geologic setting.
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 bemercially likewise, quartz/calcite will be gangue minerals associated with say an ore of copper
