  • Effect of Particle Size on Gold Flotation Recovery

    The first factor in such flotation studies is the quantification of what the limitations are of particle size on the flotation process. Some unique studies have been conducted by this author at a number of plants. Figures 1 and 2 show the results of a kinetic study done on a free gold ore from Africa.

  • Flotation of Fine Gold Particles by the Assistance of Coal

    This paper describes the use of coal-oil agglomerates in flotation to increase the gold recovery from an ore containing fine gold particles. The effects of operating parameters on gold flotation recovery such as oil type, particle size of agglomerating material, agglomerate/ore and oil/ore ratios were investigated. The studies showed that petroleum oils are more effective than vegetable oils.

  • The Effect of Collectors Type on Gold and Silver

    Flotation has been applied on ores containing free gold and silver particles for many years. The flotation efficiency of gold and silver particles depends on the modifiers and collectors. This paper presents the results of the effect of different collector combinations on gold and silver recoveries from lead and zinc ores by flotation.

    Therefore, the size effect can be explained as an increase in the collision efficiency and adhesion for increasingly coarser particles up to a point where the weight factor prevents levitation. Higher values of rate constants obtained in the modified column flotation improve fluorite recovery without much affecting the concentrate selectivity.

  • Particle Size Analysis for Mining and Minerals

    The resulting forces will cause particles to move depending on particle mass. Thus small particles are moved further than large particles. Furthermore, particle charge is a surface phenomena and the larger surface area of fine particles will tend to have a higher charge. These size effects can lead to separation by size rather than composition.
