Review on Beneficiation Techniques and Reagents Used for
In this review, the dominant techniques for the beneficiation of phosphate ores are introduced. Moreover, the factors that affect the flotation of phosphate ore, including the properties of mineralogy, flotation reagents (depressants and collectors) and flotation medium, were systematically analyzed.
concentration of amines, which can be generally recycled for the further flotation process. By using the amine containing recycled water, the same flotation results were noticed by saving nearly 50 % of the collector amount. Key words: recycling of amines, reverse flotation, process water recycling, iron ore IMWA Symposium 2001
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.
IRON ORE FLOTATION, THEORY AND PRACTICE. In order to obtain purified ferriferous concentrates, in iron ore processing, the reverse flotation of silica and silies has been tested successfully by both ionic and anionic reagents ( Pradip et al. 1993).
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 that these particles attach themselves to the air bubbles and are carried to the surface,
