In the second stage of processing the phosphate mixture, the slurry is sent to a flotation plant, where an agent is added to the mix which coats the phosphate particles. Air bubbles are introduced, and the chemically coated phosphate adheres to the bubbles, floating on the surface of the water, while the sand drifts to the bottom of the tanks.

The literature on the processing of phosphate rocks by flotation is critically reviewed. Commonly used collectors, depressants, auxiliary reagents, and their mixtures in the flotation of the phosphate ores were tabulated. The advantages and disadvantages of the reagent type and structure (e.g., ionic and nonionic) on flotation were criticized.
A process for dressing phosphate ores with gangues containing carbonates, by flotation, wherein the phosphates and carbonates contained in the ore to be treated are separated by subjecting the ore to a reverse flotation treatment utilizing a combination of reagents comprising a carbonate flotation collector and agents which modify the surface physical and chemical properties of the phosphate ...
In general, phosphate ore is processed by flotation to reduce the content of the gangue minerals, which typically consists of quartz, feldspar, mica, calcite, dolomite, etc. The Axis House phosphate reagent range can be successfully applied to efficiently separate phosphate and gangue mineral during the flotation process.
Phosphate Ores Silver Flotation Process Energy Saving. phosphate flotation calcination plant Even though fatty acids and amines are the most commonly used collectors in direct and reverse flotation of phosphate ores respectively other types of collectors are also available for flotation of phosphate ores as given in Table 2 An oily collector eg fuel oil is mostly used together as collector or ...
