same in the concentrate, 68.5 and 69.0 %, respectively for the reverse cationic and anionic flotation. The magnetite grade in the iron concentrate of the anionic flotation is increased up to 26.0% while the grade of non-metallic minerals is decreased to 1.2%.

The recovery of sericite in flotation concentrates: Mineral

Sericite is a fine grained muscovite mica, which is widely distributed in nature. It commonly occurs in many base metal ores, where it can become a major diluent in the concentrates produced from these ores, as well as in igneous rocks. It can be strongly recovered in flotation froths under circumstances where it is both wanted and unwanted.
