S2 RANGER, XRF Lab Report

Phosphate rocks have a wide industrial use as raw material for phosphorous containing materials. Apatite, a mineral with a high calcium phosphate content, is one such phosphorous source and is often used for the production of phosphoric acid which is later used to produce fertilizers. Indeed, approximately 90 % of industrially mined phosphate rocks are used for the production of fertilizers and animal feed supplements.

As available sources of high-grade phosphate ores are declining, the beneficiation of lower grade ores by washing, flotation and calcining is becoming more and more important. With such increasing demand for economical process optimization, the analysis of major and minor elements in phosphate rocks (see Fig. 1) is getting more and more important.
