This work presents and discusses the influence of the surface tension (y LV) of methanol/water mixtures on the flotation response of apatite versus gangue minerals conditioned with flotation reagents (75 g/t cornstarch and 100 g/t Berol 867) at pH 10.6. Berol 867 is a collector composed of sodium alkyl sarcosinate plus nonionic surfactant.
The gangue minerals consist of the silicate minerals such as pyroxene, olivine, plagioclase and some secondary minerals. The analysis of apatite by EDX showed the presence of fluor-apatite in the ore.
SEM and EDX provide for much higher magnifications and allow close examination of textures of phosphate and gangue mineral surfaces. XRD is used to identify minerals, qualitatively estimate their concentrations, and determine the unit-cell dimensions of the apatite. Each mineral has a unique XRD pattern composed of a series of peaks.
I want explanation in ore processing of flotation of rare earths ore monazite ex which adequate collector and which depressing for minerals of gangue to knowing oxides, carbonates silica and apatite.And another question how of extracting monazite from apatite?
Maltesh et and the sparingly soluble gangue minerals. al  proposed the formation of The poor selectivity in these systems was hydrogen bonds between fluor atoms, attributed by Hanna and Somasundaran present in the fluorapatite lattice, and  to similarities in electrokinetic, oleate as the adsorption mechanism for solubility, and surface ...
The 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). The concentration of apatite involves grinding of the carbonatite, removal of magnetite with a magnet drum,
mainly due to the presence of fine particles (less than 25 µm) of silica and apatite in the concentrates of magnetic separators and flotation circuits. In this study, the removal of very fine gangue minerals from iron concentrate of the Chador-malu processing plant was investigated using a laboratory hydroseparator.

Floatability of apatites and gangue minerals of an igneous phosphate ore. the major gangue minerals were also selected for the study quartz, a pyroxene (augite), altered micas (vermiculite), calcite and dolomite. at pH 10.5, add positive surface charges to apatite and gangue minerals, due to hydroxicomplexes specific adsorption.
In favorable circumstances, what would otherwise be gangue minerals (quartz, potassium feldspar, albite, and muscovite) can be mined along with lithium and (or) tantalum as coproducts. Most LCT pegmatites are hosted in metamorphosed supracrustal rocks in the upper greenschist to lower amphibolite facies.
Where aegirine augite is the dominant gangue mineral, apatite is common, bastnaesite is usually the dominant REE mineral, and martite or magnetite is the dominant Fe ore mineral. c. Mixture of types a and b, consisting of monazite, granular hematite, and magnetite, and both aegirine and fluorite as associated gangue minerals (fig. 11).
Abstract. 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.
Skarn deposits have typical skarn Gangue minerals but also contain ore minerals in abundance which are of economic importance. Skarn deposits are therefore classified by their dominant economic element, such as copper (Cu) skarn deposit, or molybdenum (Mo) skarn deposit to name a few.

Apatite is the most common phosphate mineral, and is the main source of the phosphorus required by plants. The bones and teeth of most animals, including humans, are composed of calcium phosphate, which is the same material as Apatite.
The main gangue minerals are quartz, apatite, dolomite and fluorite etc. Host strata are quartzite, slate, limestone, and dolomite. Dolomite is the main host rock.

Apatite is the defining mineral for 5 on the Mohs scale. Hydroxyapatite, also known as hydroxylapatite, is the major component of tooth enamel and bone mineral. A relatively rare form of apatite in which most of the OH groups are absent and containing many carbonate and acid phosphate substitutions is a large component of bone material.
