sulphide which is not concentrated by froth flotation process

M.G. Aylmore, in Gold Ore Processing (Second Edition), 2016 5.1.1 Platsol™ Process. The Platsol™ process was originally developed in collaboration with the University of British Columbia, Kane Consultants Ltd., and Lakefield Research in Canada for the treatment of flotation sulfide concentrate for Polymet Mining Company in Minnesota and was tested on similar types of concentrate materials

    Sulphide ores are concentrated by froth flotation

    The single most important operation used for the recovery and upgrading of sulphide ore. Only sulphide ores are concentrated by froth flotation process because pine oil selectively wets the sulphide ore and hence brings it to the froth. The sulphide ores preferably wetted by the oil and the gangue with the water. Hence A is answer

    The middlings stream is subjected to flotation to recover nickel sulphide which is sent to final concentrate, and reject or depress magnesia which undergoes gravity separation to concentrate the MgO. It has been discovered that a large proportion of the MgO minerals in the concentrate are contained in the 30 to 100 micron size fraction and that they are well liberated making physical separation possible

    Why Only Sulphide Ore Is Concentrated By Froth Flotation

    Froth flotation - Wikipedia, the free encyclopedia. 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
