Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

It was reported earlier that francolite and dolomite from south Florida deposits cannot be selectively floated using conventional conditioning with sodium oleate as the collector. However, dolomite could be separated from francolite if the minerals were first conditioned at pH 10 followed by reconditioning at a lower pH. An optimum separation was achieved after reconditioning at a pH below 4.5.
Get PriceThe Froth Flotation Machine and its operating principles are universally used for all types of flotation problems.This machine finds a wide acceptance due to its flexibility in construction, which allows the machine to be adjusted to handle pulps with divergent physical characteristics, as well as the common and intricate metallurgical problems which confront the present day operator.

Get PriceFroth flotation is widely used as an effective method for separating apatite from dolomite. However, it is of difficulty to realize the efficient separation of apatite and dolomite using the traditional fatty acid collectors without any depressants due to their similar physicochemical properties.

It is well documented that flotation has high economic viability for the beneficiation of valuable minerals when their main ore bodies contain magnesium (Mg) carbonates such as dolomite and magnesite. Flotation separation of Mg carbonates from their associated valuable minerals (AVMs) presents several challenges, and Mg carbonates have high levels of adverse effects on separation efficiency.
