Gold Ore Flotation MACH reactor Metallurgical Tech

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.

Froth Flotation and Gold Extraction - Manhattan Gold

2014-7-23  Most methods of water-based gold extraction are dependent on gold’s lack of buoyancy to work. However, froth flotation uses a different property of gold to separate it from ore. Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water).
