Adsorption Mechanism of Mixed Cationic/Anionic Collectors ...

The adsorption mechanism of mixed cationic C12 amine and anionic sulfate / oleate reagent schemes was examined through Hallimond flotation studies using pure quartz and hematite minerals. The flotation response of both quartz and hematite with cationic and anionic collectors in isolation and with mixed cationic / anionic collector systems was evaluated as well.

Hematite - Wikipedia

Hematite, also spelled as haematite, is a common iron oxide with the formula Fe 2 O 3 and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).
