Jan 02, 2012 · The two anionic flotation routes developed by Hanna Mining and Cyanamid, direct anionic flotation and reverse anionic flotation routes, are also being used in the iron ore industry. The history of iron ore flotation started with direct flotation of iron oxides using anionic collectors such as petroleum sulphonate, fatty acids and hydroxamates.
The iron ore tailings separation characteristics of the iron ore fines of this region slurry (50% solids by weight) is conditioned with sodium with special reference to their impliions on beneficiation in hydroxide as pH regulator, causticised starch ( kg/t) as general and flotation in particular can be found elsewhere [18 depressant ...
May 01, 2007 · 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 ...
Feb 01, 2005 · 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.
The pneumatic flotation technology was evaluated in the reverse flotation of quartz from an iron ore sample of the Iron Quadrangle, Brazil. Bench and industrial scale tests were conducted in pneumatic flotation machines at low residence time. Both tests were carried out in open circuit stages with the objective of comparison with mechanical cells.
Froth flotation chemicals play a major role in the mining and processing of mineral ores. With the increase in consumption of base metals (such as iron, steel, aluminum, etc.) and precious metals (such as silver, gold, and platinum), mining activities for the aforementioned metals have surged globally.
With an ore body 4kmlong, 80mthick and reaching a depth of 2km, LKAB's Kiruna is the world's largest, most modern underground iron ore mine loed in northern Sweden. Since mining began at the iron ore operation more than 100 years ago, LuossavaaraKiirunavaara AB (LKAB) produced over 950Mt of ore, yet only onethird of the original ore ...

Metal Mine, v. 11, p. 179−182, 2008. investigated the reverse flotation of oolitic iron ore from Hubei, China region, previously subjected to a reductive calcination and were able to obtain a concentrate with % Fe and % P. They concluded that the result is more effective than when using flotation, in ore, without treatment.
Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey ParrottSheffer, Research Editor.
Kaunisvaara iron ore mine is situated 100km north of the Arctic Circle in Norrbotten, Sweden. The mine is 100% owned and operated by Canadian mining company Northland Resources. It comprises two iron ore deposits, Sahavaara and Tapuli, loed four kilometres apart. The definitive feasibility study of the mine was completed in September 2010.
