Froth Flotation of Iron Ores sapub

02/01/2012· Although the reverse cationic flotation route has become the most popular flotation route in iron ore industry, the direct flotation of iron oxides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan, U.S.A., a hematite ore is upgraded from 36.5% Fe to 65.4% Fe with a Fe recovery of 82.5% using the direct flotation

Iron Ore Reverse Flotation Introduction Xinhai

In iron ore direct flotation process, a sort of direct flotation reagent is added and then works under specific conditions. The floating material is mainly iron concentrate. On the contrary, iron ore reverse flotation uses reverse flotation regents to work under given conditions, and its floating material is mainly gangue mineral.

An overview of the beneficiation of iron ores via reverse

10/03/2014· Research regarding iron ore flotation began in 1931, demonstrating that reverse cationic flotation is a very efficient method for beneficiating oxidised iron ores. This method can also be applied to reduce the silica content in magnetite concentrates obtained using wet low-intensity magnetic separation. Several studies describing the processing of iron ores via reverse cationic flotation are

Impurity Removal in the Reverse Flotation of Iron Ore

In 2010, CSIRO investigated the use of a reverse anionic flotation process for Vale iron ore. Batch laboratory flotation studies conducted on Vale samples showed significantly reduced reagent costs and improved recovery of iron. In this work, the flotation behaviour of the different impurities in the Vale iron ore sample using reverse cationic and reverse anionic flotation processes is

The entrainment effect on the performance of iron ore

01/10/2016· Iron ore reverse flotation requires mass recoveries to the froth product in the order of 30–35% whereas traditional sulphide flotation concentrates the values into about 5% of the total mass. It is likely that the mechanical cells used in iron ore flotation have evolved to the conditions measured here (gas rate, froth depth) in order to ensure complete recovery of the SiO 2 to the tail
