Calcium Phosphate Mineral - an overview

Apatite is a calcium–phosphate mineral, and because P has no stable isotopes, the uptake dynamics can only be studied via the Ca ion (or potentially the 18 O/ 16 O in the phosphate group). In most rocks and soils apatite is the sole primary P source. However, its contribution to the soil solution Ca pool is minor compared with other minerals.

Titanite Ores of the Khibiny Apatite-Nepheline

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.
