2019-3-1 · Froth flotation of apatite is one of the main methods of mining the mineral from host ores . Selecting the correct reagents is important in optimizing the process. As each deposit is composed of many different minerals, many studies have been conducted on apatite to identify the optimum conditions for separating from a specific mineral mix.
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 ...
Geological setting and mineral composition of (apatite)-nepheline-titanite ore from the Khibiny massif enable selective mining of titanite ore, and its processing with sulfuric-acid method, without preliminary concentration in flotation cells. In this process flow diagram, titanite losses are reduced by an order of magnitude in comparison with a conventional flotation technology.
