  • Effect of Particle Size on Gold Flotation Recovery

    Natural or collectorless flotation of native or free gold is generally possible, at least to a degree, with many gold containing ores. The first factor in such flotation studies is the quantification of what the limitations are of particle size on the flotation process.Variance relationships between the masses, grades and,masses, grades and particle sizes for gold ores from the Witwatersrand A set of data on the particle size range and gold assays for a pilot scale trial on the crushing of a low grade gold ore was used to generate a statistical model relating the variance of the assays at particular sizes to the mass of the samples. The ore was the accumulated waste over many years from operation of a large

  • Ore particle breakage behaviour in a pilot scale

    The particle size effect on product fineness indicator t 10 is not significant for Ore A, but is more pronounced for Ores B and C. Subjected to the same specific energy, the coarser particles produced the larger t 10 values for Ore B and C.Effect of particles size range on iron ore flotation ,The flotation processes for iron ore, either in mechanical cells or in columns, are fed with particles with sizes between 10 and 150pm, being the slimes removed as overflow in classification cyclones.
