Draslovka a.s., a provider of sustainability-led technologies, reagents and services for mining and the energy transition, has progressed its previously announced partnership with Barrick Gold and, today, announces the start of commercial use of its revolutionary glycine leaching technology for gold, GlyCat™, at Barrick’s Buylanhulu operation in Tanzania.

In addition, Draslovka and Barrick’s strategic partnership will now include a broader testing program in 2024 that will span multiple mining sites.

At Bulyanhulu Gold Mine, the GlyCat pilot program has led to an 80% reduction in cyanide consumption while achieving gold recoveries that are comparable with traditional cyanidation, Draslovka says. With GlyCat as part of the process, the mine’s tailings show undetectable levels of WAD and are free of cyanide, thereby reducing detoxification requirements and costs.

Pavel Bruzek Jr, CEO of Draslovka, said: “This licensing agreement follows a highly successful pilot programme that proved the major benefits GlyCat offers to the gold mining industry. GlyCat provides significant economic and sustainability benefits at a time when the future of mining is conditional on cost savings, sustainable operations and securing social license to operate. I look forward to continuing to work with Barrick and am confident others in the sector will soon see that GlyCat is revolutionary and its development will enable a major shift for the gold mining industry through massive economic and environmental benefits. Barrick was the first major mining company to recognise the potential glycine leaching offers and it is a pleasure and honour to work with the team on its commitment to sustainable operations.”

Simon Bottoms, Barrick Mineral Resource Management & Evaluations Executive, added: “The application of GlyCat technology within our operations has significant potential to deliver improved operational efficiencies and cost savings, whilst also improving our environmental legacy. Consequently, we are very pleased to embark upon this strategic partnership with Draslovka to take advantage of this innovative technology across our global operations.”
