In general, apatite is the most significant phosphate ore extracted. Lately, apatite has also become a topic of interest for rare earth element (REE) recovery (Owens et al., 2019, Sun et al., 2015, Wu et al., 2018).With the growing demand for this mineral and the decreasing or challenging supply, processing tailings from an Iron Oxide Apatite (IOA) ore beneficiation …

Hematite is the most important iron ore due to its extensive distribution and significant iron concentration [6], [7], [8]. Froth flotation is proving to be a highly efficient technique for separating and concentrating hematite [9]. According to the value of mineralized , it can be divided into direct flotation and reverse flotation.

Nevertheless, ether amines or diamines derived from alcohols and acrylonitrile are most suitable for iron ore treatment. Frothers Frothers, as defined by flotation operators, are compounds used specifically for creating a flotation froth. However, most collectors used in iron ore processing produce adequate froths.
