magnetic flotation of iron ore

Froth Flotation of Iron Ores - article.sapub.org

2012-1-2  With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

Characterisation and magnetic concentration of an iron

2019-1-1  Based on the ore characteristics (e.g. particle size, mineralogy and grade), gravity concentration (jig and Humphreys spiral), magnetic separation (low and high-field) and inverse cationic flotation (especially applied to pellet feeds) are used [3], [4]. It is estimated that for each tonne of beneficiated iron ore, 400 kg of tailings are produced.

2021-11-24  Froth flotation machine is generally used for the concentration of sulphide ores. The principle behind froth flotation process is that sulphide ores are preferentially wetted by pine oil whereas gangue articles are wetted by water. In this process, the suspension of a powdered ore is made with water. Collectors like pine oil, fatty acids and ...
