Apatite–Calcite Flotation Separation Using Sodium N

Froth flotation is a commonly utilized beneficiation technique for effectively separating apatite from other gangue minerals, such as calcite. It is difficult to achieve good separation with fatty acid collectors due to their similar interactions with apatite and calcite. In this work, sodium N-lauroyl sarcosinate (SNLS) was used as the collector for the …

The dominant presence of calcite in the limestone mine waste is evidenced by the highest percentage of CaO (72.12%) (Table 3). SiO 2 (1.14%) was also found in the sample, which was originating from akermanite. The high percentage of CaO indicated that the limestone waste is rich in calcite mineral (Han et al. 2015).
