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.

This would be reflected in froth color and bubble size. Both are dependent upon the mineral that is being collected. If however there is too much of the modifying agent being used then the froth MAY or MAY NOT reflect this in color as well. The reagent being used and the mineral being collected will dictate the characteristics of the indication.

Flotation Collectors for Industrial Minerals. Arkema specializes in developing custom-formulated flotation collectors to maximize the grade and recovery of industrial minerals. Collectors, some of the most important reagents used in the froth flotation process, are used to modify the surface properties of minerals to control how they float.
Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.
