(or) explainthe concentration of copper pyrites and galena ores. answer froth flotation this method is commonly used to concentrate sulphide ores such as galena (pbs), zinc blende (zns) etc. in this method, the metallic ore particles which are preferentially wetted by oil can be separated from gangue.why is the froth floatation method selected for theapr 05, · name the substance used as depressant in the separation of two sulphide ores in froth floatation method. asked oct , in chemistry by sudhirmandal ( 53.6k points) cbsefroth flotation froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.this is used in mineral processing, paper recycling and wastewater treatment industries. historically this was first used in the mining industry, where it was one of the great enabling technologies of the th century. (i) copper pyrite, ltbr. (ii) siver glance or argentite, 1 froth flotation fundamental principles1 froth flotation fundamental principles froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. the particles with attached airfile size 659kbflotation the past, present and future of mineralfor instance, theres a big debate in the nickel market about where nickels going to come from for future electric vehicles. there are two main types of nickel resources sulphides and laterites (oxides). flotation can be used to concentrate sulphide nickels upfroth flotation processpreparationoriginpurpospesignificancechemistrytypesapplicationseffectsmechanismdefinitionsnomenclatureintroductionvariationscostadvantagesthe froth flotation process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (waterrepel) individually to carefully separate them from one another and the slurry they are in. for this purpose we use chemicals/reagentssee more on explain the purification of sulphide ore by frotha mixture of water, pine oil, detergent, and powdered ore is first taken in a tank. a blast of compressed air is blown through the pipe of a rotating agitator to produce froth. the sulphide ore particles are wetted and coated by pine oil and rise up along with the froth (froth being lighter). the gangue particles wetted by water sink to the bottom of the tank (water being heavier).nacn used in the froth flotation method for thein froth floatation process for the purification of oresfroth floatation process used for the concentration ofsee more resultssamacheer kalvi th chemistry guide chapter 1 metallurgydec , · which type of ores can be concentrated by froth floatation method? give two examples for such ores. answer sulphide ores can be concentrated by the froth floatation method. e.g., copper pyrites (cufes 2 h 2) zinc blende (zns) galena (pbs) question 5. describe a method for refining nickel mond process for refining nickel (pta 3) answerexplain the purification of sulphide ores by froththe purification of sulphide ores by froth floatation method this method is used for the concentration of sulphide ore such as galena (p b s), zinc blende (z n s) and copper pyrites (c u f e s 2 ) to water tank, finely divide ore is added. pine oil, eucalyptus oil, xanthates or fatty acids etc are added. compressed air is passed through watermineral processing flowsheetsmar 08, · the mineral processing flowsheets shown on the following pages are based on actual data obtained from successful operating plants. metallurgical data are shown in these flowsheets which incorporate crushers, grinding mills, flotation machines, unit flotation cells, and selective mineral jigs as well as other standard milling equipment. the flotation machine, the selective mineral jig
