The basic principles of desilication of bauxite ores by reverse flotation are described. It is pointed out that the technical key of the reverse flotation for bauxite ores lies in the intensified collection of aluminum silicate, the selective depression of diasporite, the selective dispersion of slimes and the selective grinding of minerals.

1. Introduction. Flotation is usually employed to remove silicate as the main impurities from many ore types, especially iron ores. Iron oxides can be concentrated either by direct flotation, using anionic collectors, or reverse flotation of siliceous gangue with both cationic and anionic collectors .

In reverse flotation, proper reagents induce the pay minerals to become hydrophobic (water repelling) and the waste minerals to become hydrophilic (water attracting). Aeration is added through spargers at the bottom of the flotation cell. The bubbles attract and then float the waste minerals, leaving the pay minerals in the underflow.
Reverse flotation involves the flotation of ash forming minerals which means that the collectors used should be such that they make the mineral matter hydrophobic in nature. Some of the most common minerals found in coal are quartz, clay minerals (like kaolinite, illite etc.), feldspar, carbonates such as calcite, siderite and dolomite, and sulphide …
The main issue is process water management. You will need a separate water circuit for the pyrite flotation circuit and not return the water recovered from this circuit to the head of the magnetite circuit if flotation separation is being practiced (would expect magnetic separation if it is magnetite).
Several studies describing the processing of iron ores via reverse cationic flotation are reviewed. The predominate role of the pulp mineralogy, as well as the type and molecular structures of the collectors and depressants, on flotation is discussed critically.
