Some iron ore processing plants [1] combine the two approaches to produce the iron oxide concentrate destined to the steel producers. This paper deals with the gravity concentration of iron ores. Canadian processors recover coarse hematite using spiral concentrators. Spiral concentrators have been used in the industry for more than 70 years [2].

Materials and methods Vallourec s beneficiation plant produces concentrated iron ore lumps and fines in Pau Branco mine 6 Tailings are composed of both fines gt 45 m and ultrafines lt 45 m Ultrafines are generated from the desliming cycloning of the magnetic concentration process and fines are the rejects of this process
concentration process or as a final concentration stage to ensure a highgrade product. In the flotation process, air is bubbled through a suspension of fine iron ore in water to which a small quantity of flotation reagent is added. This reagent modifies the surface of either the iron oxide or the principal gangue component, normally silica, so

· Purifiion concentration process is the process of using surface tension properly, magnetic or electrical separation to remove the unwanted impurities which are chemically combined or mixed with ore to increase the percentage of iron in the ore. Oredressing process is also carried out to improve the chemical properties of ores by roasting ...
· The first step in metallurgy is to remove these unwanted impurities from the ore, to get a concentrated ore containing a much higher percentage of the metal. The method used to remove gangue from ore depends on the physical or chemical properties of the gangue and ores. Some of the methods used in the concentration of the ore include, 1.
Based on the iron ore processing experience and necessary processing tests, Prominer can supply complete processing plant combined with various processing technologies, such as gravity separation, magnetic separation, flotation, etc., to improve the grade of TFe of the concentrate and get the best yield.
