GoldOre Inventors of the MACH REACTOR

The MACH REACTOR TM has yielded significant recovery benefit for our operations and is a valuable and integral part of our circuit. Client 1 Having heard of the MACH through word of mouth we contacted Gold Ore to assist with our DO levels and ended up with a bespoke installation that released additional gold locked in sulphides, reduced preg-robbing activity as well as our gold soluble losses.
