Flotation of Iron Ores: A Review: Mineral Processing

2019-11-19  A novel stepped flotation technique is discussed for the treatment of carbonate-rich iron ores. The necessity of desliming to enable effective flotation is discussed in detail. Selective flocculation desliming is discussed in particular detail as it is the primary deslime methodology used in industry.

2012-1-2  The history of iron ore flotation started with direct flotation of iron oxides using anionic collectors such as petroleum sulphonate, fatty acids and hydroxamates. In 1950s, the direct flotation route was integrated in plants, including Humboldt Mine (USA, 1954), Republic Mines, (USA, 1956), and Anshan Iron & Steel Corporation, (China, 1958).

Froth Flotation of Iron Ores article.sapub

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.

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
