The final step in mineral separation is by preferential flotation of mineral fractions by heavy liquid. Nonmagnetic fractions first undergo separation by sodium polytungstate (SPT; 2.85 g/cm3) and finally by methylene iodide (MEI; 3.3 g/cm3). At the end of separation, the final fraction should contain minerals such as zircon, apatite, monazite ...

Apatite Trace Element Compositions: A Robust New Tool

The crystal structure and chemistry of apatite results in relatively high mineral-melt and mineral-fluid partition coefficients for many trace elements (Hughes and Rakovan, 2002; Pan and Fleet, 2002; Prowatke and Klemme, 2006).Calcium, a large cation, has two structural sites in apatite (Ca1 and Ca2), which are capable of accommodating high concentrations of many trace elements, including Na ...

Apatite as an alternative petrochronometer to trace the ...

2021-8-19 · Apatite is another ubiquitous accessory mineral in many rocks, especially Ca-rich igneous and metamorphic rocks, as P 2 O 5 has a low solubility in silicate melts and only a small amount of phosphorus may enter the crystal lattices of other rock-forming minerals (Chew et al. 2011; Cao et al. 2012; Chew and Spikings 2015; Pochon et al. 2016 ...

Mechanism of calcium lignosulfonate in apatite and ...

2021-3-4 · Since the physical and chemical properties of apatite and dolomite can be similar, the separation of these two minerals is difficult. Therefore, when performing this separation using the flotation method, it is necessary to search for selective depressants. An experimental research was performed on the separation behavior of apatite and dolomite using calcium lignosulfonate as a depressant ...

An Integrated Apatite Geochronology and Geochemistry

2018-4-6 · Heavy minerals comprise only 1% of the non-framework sediment load, mostly pyroxene (Table 1), reflecting the presence of a small basanitic pipe in the catchment (Figure 2). Only 4.5% of the much-reduced heavy mineral budget is apatite, as a result only 45 grains were found for LA-ICP-MS analysis in a sample several kilograms in weight.
