An overview of the beneficiation of iron ores via reverse ...

2014-3-10  Reverse cationic flotation is the most used flotation method of iron ore beneficiation. Ether amines and starches are usually used as collectors and depressant, respectively. Selective depressants for Fe-bearing silicates deserve further investigations.

Reverse column flotation of iron ore - Home - Springer

2007-5-1  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 ...

Impurity Removal in the Reverse Flotation of Iron Ore

Since the 1970s, Vale has been using reverse cationic flotation to remove siliceous impurities from its iron ores. Whilst this flotation process has operated effectively for many years, it suffers from the problems of high reagent costs and high metal loss.In 2010, CSIRO investigated the use of a reverse anionic flotation process for Vale iron ore.

Collecting Agent–Mineral Interactions in the Reverse ...

Froth flotation has been widely used in upgrading iron ores. Iron ore flotation can be performed in two technical routes: direct flotation of iron oxides and reverse flotation of gangue minerals with depression of iron oxides. Nowadays, reverse flotation is the most commonly used route in iron ore flotation. This review is focused on the reverse flotation of iron ores,

Reagents in iron ores flotation - ScienceDirect

2005-2-1  The plant practice of iron ores flotation involves the conventional reverse cationic route, with ether amines employed as quartz collector and gelatinised corn starch used as iron oxides depressant. Options already incorporated in industrial operation, concerning the collector, include combining mono-amines with di-amines and partial substitution of amines by fuel oil.

2013-5-1  According to Brandão (2005), the selectivity of iron ores reverse cationic flotation observed in laboratory and in plant practice is based on the quantitative aspects of collector and depressant adsorption, rather than on qualitative aspects. Starch adsorbs extensively on hematite and at lower intensity on quartz.
