We are completely blown away by the effect of the MACH REACTOR TM on our flotation circuits and whilst we have healthy debate over the mechanisms at play we gladly accept the vastly improved recoveries and grades. We view ourselves as being an instrumental industry partner to Gold Ore to help establish the best applications of the MACH REACTOR TM in the PGM industry.
Click to chatThe flotation of gold and silver minerals is mostly carried out in alkaline pulp medium but for some gold-bearing pyrite and pyrrhotite it is suitable for flotation in weak acid pulp medium. Oxygen has an effect on the flotation process of gold-silver sulfide ore oxidized to different degrees.
