ideal scenario, where there is 100% separation and recov-
ery of pure carbonated fluorapatite. In this context, the
ratios observed in the heatmap indicate varying degrees of
separation efficiency. The FrOC at pH 6 achieves the high-
est enrichment ratio of 1.64, indicating relatively effective
separation, although still below the optimum. This suggests
that at lower pH levels, the FrOC enhances apatite recovery
more effectively than other collectors. In contrast, MOC
and ROC exhibit lower ratios across all pH levels, with
MOC at pH 9 showing the lowest ratio of 1.14, suggesting
poor separation efficiency. Overall, the results demonstrate
that while the collectors didn’t achieve perfect separa-
tion, FrOC at pH 6 approaches higher efficiency levels,
