    why only sulphide ore is concentrated by froth flotation

    The process was not froth flotation but used oil to agglomerate (make balls of) pulverised sulphides and buoy them to the surface, and was patented in 1898 with a descriptionIn the mining industry, the plants where flotation is undertaken to concentrate ore are generally known as concentrators or mills

    Basic Principle of Froth Flotation Process. The process of froth floatation starts with the Comminution process in which the surface area of the ore is increased. First of all, the ores are crushed into very fine powder sized particles and mixed with water. The mixture obtained is called Slurry

    Jan 20, 2021 · “The single most important method used for the recovery and upgrading of sulfide ores”, that’s how G. J. Jameson described the froth flotation process in 1992. And it’s true: this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different categories of hydrophobicity that are increased by

    Dec 22, 2020 · The principle behind froth flotation process is that sulphide ores are preferentially wetted by pine oil whereas gangue articles are wetted by water. In this process, the suspension of a powdered ore is made with water. Collectors like pine oil, fatty acids and xanthate are added to it. Froth stabilizers like wrestles and any line stabilized the froth. The mineral particles become wet by oils while gangue …

Then air is passed through this mixture. This results in the agitation of water in tank, which cause the sulphide ore particles to stick with the oil and rise to the surface in the form of froth. The gangue particles being heavier remain behind at the …
