Froth Flotation of Iron Ores

the most popular flotation route in iron ore industry, the direct flotation of iron ox ides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan, U.S.A., a hematite ore is upgraded from 36.5% Fe to 65.4% Fe with a Fe recovery of 82.5% using the direct flotation route.

2020-5-1 · 1. Introduction. Flotation is a selective process for separating minerals from each other based on particle hydrophobicity. The flotation separation efficiency depends on the recoveries of the mineral species by both true flotation and entrainment (Cilek, 2009, Neethling and Cilliers, 2009, Wang et al., 2015).Both chemical variables and hydrodynamic conditions within the flotation cell affect ...
