The Iso Electric Point (IEP) of monazite, apatite, ilmenite, quartz, rutile, and zircon are 5.3, 8.7, 3.8, 3.4, 6.3, and 50.1 respectively. Thermodynamic parameters of ...
More Details· A phosphate ore from the Catalão mine (Brazil) poses a challenge for apatite flotation from its carbonate gangue minerals. In recent developments, selectivity has been enhanced by using CO2 instead of air. The adsorption of the sulfosuccinate collector on apatite and carbonates, with air or CO2, was studied through infrared spectrometry (FTIR, transmission mode), X-ray photoelectron ...
More DetailsThe carbonatite-hosted apatite deposit of Jacupiranga is located in southeastern Brazil. The major styles of apatite mineralization are veins or veinlets, small pods or patches, disseminated apatite, and massive aggregates (locally).

More DetailsAbstract. Gangue minerals from hydrothermal deposits (apatite and carbonates) and their host rocks from three different volcanic areas (SE Spain, La Serena and Melipilla in Coastal Range of Chile) have been studied for broad elemental compositions.
More DetailsWhat is Apatite? Apatite is the name of a group of phosphate minerals with similar chemical compositions and physical properties. They are an important constituent of phosphorite, a rock mined for its phosphorus content and used to make fertilizers, acids, and chemicals. Apatite has a relatively consistent hardness and serves as the index mineral for a hardness of five in the Mohs Hardness Scale.
More DetailsThe gangue containing polymetallic magnetite often contains silicate or carbonate minerals, associated with cobalt pyrite, chalcopyrite and apatite, etc. Generally, the combined process of weak magnetic separation-flotation is used, that is, weak magnetic separation process recovers iron, and flotation process recovers sulfide or apatite.

More DetailsMount Apatite Park, Auburn, ME Maine Geological Survey Minerals at Mount Apatite During feldspar mining the quarry workers sometimes encountered rare and unusual minerals. (The mountain is named after a phosphate mineral called apatite, which was found as beautiful deep purple crystals at the Pulsifer Quarry on the west side of the hill.
More Details· The presence of different apatite types is characteristic of igneous phosphate deposits. The flotation performances of primary and secondary apatites occurring in phoscorites, weathered phoscorites and pyroxenites were investigated. As a contribution towards the understanding of the behaviour of the flotation system, the major gangue minerals ...
More DetailsPhosphate ore is an important industry mineral resource in which apatite is the main valuable mineral. Over 90% of China''s phosphate rock is high magnesium phosphate rock, and dolomite is the main carbonate gangue mineral of it.
More Details· Apatite (Ca 10 (PO 4) 6 F 2) is the most important phosphate mineral, and flotation is the main beneficiation method to separate apatite from its major gangue mineral calcite (CaCO 3).Till date, fatty acids and their salts have been widely used as collectors in the apatite/calcite flotation separation due to their low cost and strong collecting ability, but their selectivity is limited.
More Details· the main carbonate gangue mineral of it. Flotation has been the most widely adopted technique for the separation of dolomite from apatite for this kind of magnesium (calcium) phosphate ore, and an anionic collector, such as sodium oleate, is usually used in the acidic pulp for reverse flotation [1–3]. Flotation is a separation method based ...

More DetailsApatite is often associated to ores exploited for other economical minerals, as it is the case for iron ores. For such ores, apatite is considered as a non-valuable mineral and it is discarded as gangue to the tailings ponds of the concentrator.
More Details· The minerals in this category among others include fluorite, apatite, diamonds and gemstones, ... In order to separate the minerals from gangue (the waste minerals), it is necessary to crush and grind the rock to unlock, or liberate, valuable minerals so that they are partially or fully exposed. This process of size reduction is called comminution.

More DetailsThe amount of gangue minerals seems to have no significant effect on the degree of liberation after comminution. Apatite is generally best liberated in ore types associated with silicates, regardless of magnetite or hematite dominance. From the results it can be inferred that a good degree of liberation of the minerals of economic
More Details· Apatite, a gangue mineral often associated with brannerite in uranium deposits was found to interfere with the leaching of brannerite in sulphuric acid media. Phosphates interfere with acid leaching of uranium through reducing the free acid and forming ferric phosphate species. Phosphate was also shown to contribute to the formation of a ...
