All flotation studies were carried out in a Denver D-12 sub-aeration flotation machine with a 1.2 ... In order to improve the efficiency of iron ore flotation, Tao et al. (2010) have used a depressant for clay and iron minerals. The depressant, known as GP clay binder, reduces the coating of slimes on quartz and hematite particles.
The significant applications of iron ore flotation are reviewed along with an abbreviated discussion on theory and reagent use.
Hematite, also spelled haematite, is a weakly magnetic iron ore with better floatability than magnetite and wide distribution. It is one of the most important raw materials for the extraction of iron. ... Its principle is to grind the hematite ore into a slurry by adding water to the flotation machine, and then stir and aerate to produce a ...
The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the …
