Flotation Reagents. mixtures of chemicals, commonly known as reagents, is presented for the purpose of acquainting those interested in froth flotation with some of the more common reagents and their various uses. Flotation as a concentration process has been extensively used for a number of years. However, little is known of it as an exact ...
Flotation has been developed as the principal separating process for the potash salts which generally are coarsely crystalline and free from the sodium salts at about 10 to 14 mesh. In most cases the potash is floated in the froth product and the salt, NaCl, discarded as tailings. A plus 60% K2O product is required and flotation normally will ...
THE FLOTATION PROCESS A standard flotation circuit starts by separating the scrubbed ore into a coarse (for example +20 mesh) and fine (-20 mesh) portions. To design optimum flotation circuits, we must understand your processing needs, and the technical and mineralogical characteristics of your ore. Successful flotation involves
The reverse cationic flotation is also largely used to reduce the silica content in the iron concentrate obtained through magnetic separation. It is the most efficient upgrading process for simple systems composed of hematite/magnetite and quartz (Araujo et al., 2005, Filippov et al., 2014).

The magnetic ore stays on the belt, while the gangue slides off. By eliminating non-magnetic impurities, this process is utilised to concentrate magnetic ores of iron such as magnetite and chromite and manganese (pyrolusite). A magnetic separator is used in this procedure. A magnetic separator is made out of two rollers and a leather belt.
