POWER SUPPLY AND ENERGY EFFICIENCY

GoldOre’s MACH reactor underpins the green agenda By Adrian Singh, MD of GoldOre

E nergy efficiency and decarbonisation remain a key talking point and one can hardly attend any conference in mining and metallurgy with out it being a main topic of discussion. It’s often a double-edged sword for the mining sector – with the sector itself being a huge consumer of energy, while playing a vital part in the growth of economies, especially in third world counties. Ironically, mining also has a positive role to play in the field of battery and rare earth minerals, which are key for the grow ing EV industry. There have been numerous world summits on the subject of decarbonisation and global warm ing, starting with the Paris Agreement during COP21 (Co-operation of the People) and with COP27, was held in December of 2022, being the most recent.

Faster extraction kinetics is achieved with the MACH reactor.

There it was agreed to limit the global annual tem perature rise to 1.5 0C per year and to achieve a global carbon net-zero position by the year 2050. There is still much to be done, and while there is a huge global drive away from fossil fuels and towards green energy supply, improving efficiency is equally important and top of the agenda for all industries. GoldOre offers energy efficient solution Now more than ever, companies need to scruti nise and improve their energy efficiency initiatives and this should filter down to their procurement and supply chain processes. Fortunately, GoldOre has already invested much effort into reducing the power requirement of its patented and proprietary MACH Reactor technology, which it markets primar ily into the gold, PGM, base metals and industrial minerals industries, for recovery improvement and environmental remediation. Economic recovery improvement, as obtained with the MACH, remains of paramount importance to mining operations as they strive to make the best use of available mineral resources and to minimise wastage as far as possible. The MACH is not only able to improve the recovery of difficult to treat ores, but it also reduces reagent consumption, which reduces environmental impact. Philosophically speaking, if economic recovery were maximised in an environmentally friendly manner, there would be no need to retreat tailings dams and use a sig nificant quantity of power all over again. Double handling of material is never efficient. Faster extraction kinetics with the MACH also enable a smaller plant footprint, with the knock-on effect
