The Eriez Flotation Division has supplied more than 900 flotation columns throughput the world in mineral concentrating and purification applications that include iron ore, base-metals, gold, industrial minerals, fertilizers (phosphate and potash), energy (coal and oil-sands) and specialty applications such as oil/water separation.
With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

CDTN carried out a study of the process in a column flotation pilot plant installed in the mining facilities with a slime sample, with a view to recovering this sludge using the reverse flotation technique. The aim of this experiment was to obtain a final concentrate whose Fe content assigned 66% with a SiO. 2. content below 0.8% and P lower than 0.03%. The results showed that the ultrafine ...
2015-07-10 The processing of iron ore slime by mechanical flotation has been extensively studied but it was less understood with the column flotation. So in order to achieve the grade and recovery of iron values from slimes of Indian iron ore, rich in alumina and silicate minerals, the effects of process parameters need to be explored.

The processes of iron ore flotation being either by means of mechanical cells or columns, are fed by particles whose sizes vary 10 and 150 µm, the ultrafine particles (slimes) are removed by means of cyclone, for they affect the process in a negative way, and the top size is limited to values between 5% and 10% above 150 µm.
The froth flotation process was patented by E. L.Sulman, H. F. K. Pickard, and John Ballot in 1906, 19 years after the first cyanide process patents of MacArthur and the Forests. It was the result of the intelligent recognition of a remarkable phenomenon which occurred while they were experimenting with the Cattermole process. This was the beginning. When it became clear that froth flotation ...

The role of reagents utilised in iron ores flotation is reviewed. Desliming and flotation stages should be performed at pH levels as low as possible to reduce the expenses with caustic soda. Ether amines are by far the mostly utilised class of collector. The degree of neutralisation of the ether amine is an important process parameter. The partial substitution of amine by non-polar oils seems ...
