Even though the coal reverse flotation process has some obvious advantages over forward flotation and a development period of around 50 years starting from 1960s, it is still an established route neither for ash reduction nor for pyrite removal. This indicates that there is scope of improvement and more work need to be done in order to bring the process to the commercialization stage.
Flotation is one of the most effective technologies for the up-gradation of coal fines of particle size below 0.5 mm because of the inherent hydrophobic nature of coal. Contrary to this, reverse flotation of coal in which coal particles are depressed and gangue particles floated, was developed as an alternative process to minimise the sulphur content in the coal. This method can also be ...
On the contrary, iron ore reverse flotation uses reverse flotation regents to work under given conditions, and its floating material is mainly gangue mineral. Because the density of gangue ore is smaller than that of iron ore, reverse flotation method shows a better flotation performance with lesser flotation reagents, which reduce the production costs to some extent compared with direct ...
The two anionic flotation routes developed by Hanna Mining and Cyanamid, i.e. direct anionic flotation and reverse anionic flotation routes, are also being used in the iron ore industry. The history of iron ore flotation started with direct flotation of iron oxides using anionic collectors such as petroleum sulphonate, fatty acids and hydroxamates.

X-ray photoelectron spectroscopy (XPS) was used to indicate the chemical properties of Taixi oxidized coal. The results of XPS analysis showed that Taixi oxidized coal contained many oxygen functional groups. The results of our previous studies (conventional flotation tests using diesel as collector) indicated that Taixi oxidized coal was difficult to float. A concentrate yield of 24.89% could ...

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.

1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while the particles that remain completely wetted stay ...
The cationic collector in the magnetite reverse flotation process is Lilaflot collector. When the dosage of the Lilaflot collector increase to 30-50g/t, the iron grade of the iron concentrate is up to 69.90%, the silica 2.80%, which is suitable for a direct reduction of iron concentrate. The sulfur content of the concentrate is an important indicator for the concentrate quality after magnetite ...

Its reverse flotation of magnetite where pyrite is floated. Though the pyrite concentration looks to be lower (with S<0.5% in feed) it may be worth looking at the pyrite floats around the Kalgoorlie area in Western Australia as these systems are generally highly saline (off the top of my head KCGM Fimiston and Kanowna Belle) and do employ xanthates.
