More2012-1-2 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.

Clemmons Serial No. 473,162, filed January 22, 1943, is described a process for beneficiating iron ores and products from the milling of iron ores containing calcareous and/or siliceous gangue materials wherein anionic ...
More2015-7-10 The flotation routes of iron ore can be classified into five major groups, i.e. cationic flotation of iron oxide, cationic flotation of quartz, anionic flotation of iron oxide, anionic flotation of quartz and their combination (Clemmer, 1947). Theoretically, iron oxides should be easy to

More2005-2-1 Queiroz (2003) verified that, for certain itabirite ore types, the use of attrition allows the increase of the mass recovery to the slimes and flotation concentrate fractions and the decrease of iron grade in the flotation tailings, iron grade in the slimes and SiO 2, Al 2 O 3 and P grades in the concentrate, resulting in higher figures for Gaudin’s selectivity index.

More2020-11-1 Column flotation tests were performed with iron ore slimes. The column having 5.1 cm in diameter and a total height of 6.0 m was used. The %s in the conditioning phase and in the column feeding were kept at 35% and 25%, respectively. The pH adjustment was made with sodium hydroxide.
MoreThe impurities inherent with the iron oxide minerals limited the grade of concentrates recoverable from these ores to a maximum of about 61% Fe if reasonable iron recoveries are sought. Flotation concentrates assaying 60–61% Fe and about 0.1% P with attendant iron recoveries of about 63% were achieved from Big Seam ore charges while those ...

MoreA number of Nigerian iron ore deposits have been upgraded to the specifications of concentrates for the blast furnace and the direct reduction iron- and steel-making plants. Depending on the mineralogy of the ore deposits, the techniques of oil agglomeration, magnetizing reduction, washing and scrubbing, gravity concentration, and reverse froth flotation have been utilized.
