Mineral processing - Wikipedia

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles.

and flotation concentration, as well as combinations of these processes. Based on iron content, these ores are divided into low-grade ore (iron content to 40%) and high-grade ore (iron content of 50–60% and above). The high-grade ores are coarse- and medium-disseminated, and low-grade ores are fine-disseminated (Fig. 1).
