Geology. Apatite is very common as an accessory mineral in igneous and metamorphic rocks, where it is the most common phosphate mineral.However, occurrences are usually as small grains which are often visible only in thin section.Coarsely crystalline apatite is usually restricted to pegmatites, gneiss derived from sediments rich in carbonate minerals, skarns, or marble.

Apatite 0.10 0.10 0.15 Other 0.09 0.47 0.12 Total 100 100 100 Mineral Chemistry and Elemental Distribution A variety of ore minerals commonly display a wide-range of solid solution compositions that vary among and across deposits. Both the major and trace element concentrations are important for exploration and downstream processes. Mineral ...

Blue apatite is a prized mineral specimen by rock collectors for its vibrant royal blue color. Most of the apatite rock mined throughout the world is used to produce phosphate fertilizer. It is also used to produce animal feed supplements, phosphoric acid, elemental phosphorous, and phosphate compounds for the chemical industry.

The mineral & chemical analyses implies that the approach should be to develop a process to reduce both iron & silica substantially to improve the apatite content after grinding to a fine size for better liberation. Two route of processing was attempted, i.e., direct flotation with suitable

Gravity separation is also used to separate non-metallic minerals such as pyrite, apatite, diamond and asbestos from coal measures. For those nonferrous metal ores (copper, lead, zinc, etc.) which are mainly ...

Jan 01, 2017· "Four main and three minor rare-earth-element (REE)-bearing minerals were identified and quantified in the Kiirunavaara apatite iron ore tailings using optical microscopy, an electron probe microanalyzer (EPMA) and a mineral liberation analyzer, and their chemical compositions were analyzed by the EPMA and laser ablation inductively coupled plasmamass spectrometry.

Feb 18, 2020· Flotation as the most important method is applied in phosphate ore processing to separate the valuable mineral of apatite from the gangue minerals, such as dolomite and quartz (Zhou et al., 2015). Mineral type and electrolyte environment will result in different surface electrical behaviors of different minerals, and even the same mineral ...
