Abstract: 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.

The reverse flotation of the iron ore with etheramine collector is significantly impacted when the iron-bearing silicates and the kaolinite are present in the silicates gangue mineral complex.

Corn starch has been used in iron ore flotation in Brazil since 1978. The trade name of the reagent was Collamil, consisting of a very fine and very pure product. The amylose plus amylopectin content reached 98% to 99%, dry basis, the balance being represented by minor contents of fibres, mineral matter, oil and proteins.

Flotation reagents refer to the agent that used in mineral flotation process, which can adjust the flotation behavior of minerals thus achieving a good effect of mineral separation.Currently using flotation reagents is the most flexible, effective, and convenient method of controlling flotation process.The commonly used flotation reagents can be mainly divided …

This is a very important measurement for the flotation operator. Some minerals like Iron pyrite will not float well in an alkaline flotation circuit. An alkaline solution is also slightly caustic, this will help clean the surface of the mineral. ... To control the Alkalinity of the ore some of the reagents that may be used are SLAKED LIME ...

In addition, the flotation performance is significantly affected by the quantity of flotation reagents, which has been previously studied extensively by the authors. 14,15,16,17,18 Thus, in a flotation circuit, an unsuitable reagent system leads to metal loss with reduced product quality. In the direct flotation stage of iron ores, the flotation reagent system comprises pH …

Introduction. Iron ore export plays a relevant role in the Brazilian trade flow. Brazilian concentrators employ cationic reverse flotation to concentrate iron ore fines below 105. μm.. The commonly used reagents are corn starch and ether amine, respectively, depressant and frother/collector (Araujo et al., 2005).

Water for reverse flotation of iron ore contains a significant concentration of amine flotation reagents used to remove silica particles (Batisteli and Peres, 2008; Stapelfeldt and Lima, 2001). Copper cyanide complexes are often found in water for galena–sphalerite flotation because of the addition of sodium cyanide in the milling circuit ...
