  • Froth Flotation of Iron Ores

    · Although the reverse cationic flotation route has become the most popular flotation route in iron ore industry, the direct flotation of iron oxides still appears desirable for some low grade iron ores that contain a vast amount of quartz For example, at Republic Mine, Michigan, USA, a hematite ore is upgraded from 365% Fe to 654% Fe with a Fe recovery of 825% using the direct flotation
