use of flotation in iron ore benificiation

use of flotation in iron ore benificiation

Isostearic acid, a liquid isomer of stearic acid, is used as an agent in a froth flotation process to concentrate the iron oxide in iron ores. By use of this flotation agent, the iron oxide in the ground ore is directly floated away from the remainder of the ore. The process enables a high amount of iron oxide to be concentrated from low grade ores.

US4206878A Beneficiation of iron ore Google Patents

Iron ore is beneficiated using separation steps based on mineral composition without the use of separation steps based entirely on size. In a preferred sequence of steps the iron ore is passed from a ball mill through a magnetic separator where low iron content tailings are rejected and the concentrate passed to a flotation step, where a high iron content concentrate froth is made and the ...

Application of biotechnology in iron ore beneficiation

Jan 01, 2015 Most commercially operated iron ore flotation processes, such as the one used by Samarco in Brazil, use the reverse cationic flotation method where the process waters are basic, amine is used as a quartz/silicate collector, and starch is used as an iron depressant (Houot, 1983). As with sulfide ores, the flotation reagents can be expensive and ...

beneficiation of iron ore by flotation

Beneficiation of Iron Ore Fines by Conventional Flotation, Flotation . Direct flotation of iron ore using oleic acid is relatively expensive in terms of high reagent consumption and entrapment of gan-gue minerals in the froth. Therefore. beneficiation of iron ore fines by reverse flotation using cationic collectors is gaining cess, to obtain ...

iron ore flotation water quality

Improved metallurgical performance of column cells in iron ore flotation is reported and attributed to froth washing, which reduces the loss of fine iron minerals entrained into the froth phase (Dobby, 2002). The Brazilian iron ore industry has embraced the use of column flotation cells for reducing the silica content of iron concentrates.
