Shandong 1500td Iron Ore Beneficiation Project. Xinhai increased anionic reverse flotation process of magnetic concentrate on the basis of the single magnetic separation process. Iron ore concentrate was obtained directly with a roughing, tailings were discarded with three scavenging, middlings returned to efficient thickener.
application of column flotation technology in beneficiation of iron ore fines. 5 2. COLUMN FLOTATION TECHNOLOGY AND APPLICATIONS Column flotation offers mineral processors several opportunities to significantly improve process economics. Properly designed and operated columns can deliver high recoveries and concentrate
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.
