  • Optimisation of gold recovery by selective gold

    Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the free gold can be selectively floated away from an ore

  • Biooxidation of a Refractory Gold Ore Implications of

    The Sawayardun Gold Mine, the first Muruntau type gold mine in China, was located in the south Tianshan Mountain, Xinjiang Province. The gold reserve was 127 t with an average gold grade of 2.36 g/t. Due to the high content of arsenic and antimony, the traditional flotationroastingcyanidation process was not suitable. The direct cyanidation gold extraction for the raw ore was 44.70 %.

  • Flotation kinetics of a pyritic gold ore ScienceDirect

    2011117ensp;0183;ensp;Research Highlights Flotation kinetics of a pyritic gold ore was studied with respect to particle size. Gold recovery increased by 4% with grinding from a P 80 of 205 microns to 53 microns. Second order kinetics is a much better representation of semibatch flotation. The first order flotation rate constant is independent of particle size in this range. The second order flotation rate constant

    200511ensp;0183;ensp;Early work on gold particles with copper sulfate showed no improvement in recovery but an increased rate of flotation of gold (Leaver and Woolf, 1934). More recent laboratory testwork on a refractory gold ore has shown, however, that a 5% increase in free gold flotation recovery is achievable when adding copper sulfate (Teague et al., 1999b).
