  • These Gravity Concentrators Are Great At Gold Recovery

    The “UF” or Ultra Fine Gravity Concentrator solves a very specific fine gold recovery problem, and does it very well. Some gold ores contain carbon which can interfere with the leaching process, so flotation is used to remove the carbon before leaching. However, during the flotation process, extremely fine gold particles will float with the carbon. This gold would normally be lost to tailings, but the UF has the

  • Gravity Recovery of Gold From Within Grinding Circuits

    Gold recovery using batch-type centrifugal concentrators (BCC’s) from within grinding circuits is a well established practice in many operations where the presence of gravity-recoverable-gold has been identified to be present in the ore.

  • Effect of Particle Size and Grinding Time on Gold

    The results are consistent with the fact that gold dissolution increases with the decreasing particle size but results also indicate that gold dissolution of the ore within a size interval is not significantly affected by the grinding time used for the ore size reduction. Results also show a good dissolution of the gold contained in the fine-size fractions without oxidation and lead nitrate
