In the study, it was shown that iron phosphate coatings on pyrite surfaces could be established by consuming 5% to 10% of the available pyrite, under a wide range of conditions. It was also demonstrated in the study that, iron, phosphate coatings on pyrite surfaces could prevent pyrite oxidation and acid production in, coal waste.
