New perspectives in iron ore flotation: Use of collector …
The conventional amines used in the reverse flotation of iron ore (e.g., etheramine) are cationic collectors, meaning that when in water they adopt a positive charge and adsorb to negatively charged silicate gangue minerals by electrostatic forces to promote their flotation (Filippov et al., 2014, Nakhaei and Irannajad, 2017).

Lumpy Chrome Ore Sorting Boosts Efficiency with TOMRA
The X-Ray sensor accurately establishes the density of each particle in the feed, and high-speed pneumatic ejectors separate ore with high chromite content from bare or low-grade ore at throughputs between 60 and 200 tonnes per hour. The resulting output is a high-grade product that is ready to sell, with no need for additional comminution.
