Froth Flotation of Iron Ores - CSIRO Publications

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.

Desulfuration Behavior of Low-grade Iron Ore-coal ...

The process of coal-based direct reduction followed by magnetic separation was employed to produce direct reduction iron powder (DRIP) from a refractory low-grade iron ore. The desulfuration behavior of the composite briquettes during this process was studied. Experimental results showed that this process presents advanced sulfur removal ability.

Reverse column flotation of iron ore SpringerLink

2007-5-1  The use of column flotation was considered for the “reverse flotation” of iron ore, where the gangue (quartz) was recovered in the froth product. This use of the froth for carrying the gangue mineral rather than carrying the valuable concentrate significantly changes the operational requirements of the column. The objective of this work was to determine which of several column flotation ...

Flotation applied to iron ores with complex mineralogy

A low-grade iron ore from one of the largest Mexican deposits was investigated. Flotation was performed on samples with different particle size distribution to verify the influence of liberation and evaluate iron losses in case of a possible screening prior flotation. The results show that there is a considerable difference in the quality of the final product from flotation between the samples ...
