As a starting point, and to ensure credibility and rightful ownership, GoldOre took the initiative to obtain worldwide patent protection for its MACH Reactor technology which not only reassures poten tial clients of GoldOre’s legal right to the technology, but also sets their minds at ease regarding the potential infringement of patent rights of other com peting technologies. The MACH Reactor is the gold industry’s only hydrodynamic, cavitating and self-aspirating shear reactor for gas injection into pulp with a relatively low power draw. “Patent protection is the only reliable way to ensure sustainable long-term business and is a necessary right of passage to ensure a seat at the negotiating table as well as satisfying good gover nance principles of reputable clients,” says Singh. Collaborative R&D unlocks value GoldOre has expanded its market footprint through close collaboration with clients that have serious metallurgical challenges to overcome in the fields of leaching, flotation and environmental remediation. According to Singh, it is through laboratory and semi-pilot investigations, coupled with continu ous research and development in conjunction with research (Mintek) and academic institutions, that GoldOre can provide a compelling techno-economic solution with the MACH that is hard for any potential client to ignore. “Recently, GoldOre modified the gas dosage ports on the MACH to include reagent dosage points. This has yielded huge savings in both reagent con sumptions (up to 30%), by improving the miscibility and mixing of reagents within the MACH, as well as efficiency improvements by introducing critical reagents into a high reactivity environment in the venturis of the MACH, to ensure a chemical reaction and metallurgical response that would otherwise not be possible. Most importantly, recovery improve ments of between 2 and 8% can be attained, which goes straight to the bottom line. In conjunction with

research, design adjustments have also been made to allow for the easier installation of the MACH using the existing infrastructure of thickener underflow pumps and pipelines where finances, space, flow sheet constraints and practicality do not allow for the traditional and preferred tank recirculation method of installation. The ability of the MACH to uniquely enable gas vacuum, or self-aspiration, has allowed for seamless pulp aeration when a pressurised gas supply has not been available. These small techni cal advances have made a huge impact on project outcomes and established the MACH as a tried and tested technology, with a worldwide track record and footprint for over a decade.” A tough nut to crack The South African mining industry is an extremely difficult market to break into, says Singh, adding that once the legal requirements have been satisfied, the softer aspects of reputation, track-record and cred ibility come into play. GoldOre has established itself over the past 11 years as an ethical company that is based on techni cal excellence. To this end, there have been numerous papers

The MACH’s patented technology has been developed to the highest standards.
