Ballarat, Australia – Gekko Systems, a global leader in the minerals processing industry, proudly announces the launch of the Wolff Batch Centrifugal Concentrator (Wolff), a groundbreaking technology designed to transform gold processing by utilising “dirty” water. This ‘first of its kind’ innovation enables mining companies to recycle water efficiently, addressing water stewardship and enhancing sustainability, while reducing maintenance costs and requirements.
The mining industry is committed to enhancing water management practices while also improving efficiency, safety, and productivity. In some locations, mines face the challenge of having no or very limited access to fresh water. The Wolff gravity-based, batch centrifugal concentration (BCC) system helps meet these challenges by enabling mines to operate using non-potable water, including both recycled and contaminated sources.
Sandy Gray, Founder and inventor of the Wolff Concentrator
“Water is a scarce commodity in mining and mining operations are now looking for ways to reduce fresh water consumption,” said Sandy Gray, Co-Founder and lead inventor at Gekko Systems. “The Wolff enables mines worldwide to improve resource availability and recovery while enhancing sustainability through the use of recycled water.”
Traditionally, maintaining batch centrifugal concentrators (BCC) involves complex and costly procedures, characterised by significant downtime and safety risks associated with crane operations. The Wolff transforms this process with its unique patented bowl design, reducing maintenance time and eliminating the need for cranes during bowl changes, resulting in a significantly safer working environment for mine personnel.
Kaiser Reef [ASX: KAU], has partnered with Gekko Systems in a pilot project using the Wolff at their processing plant in Maldon, Victoria. The collaboration is yielding exceptional results, including improved gold recovery, a decrease in the stripping requirements of carbon, as well as a reduction in reagents consumption within the CIL circuit.
Kaiser Reef is entering into new high grade ore body that responds very well to gravity recovery. “However, we have a small throughput, so it was difficult to use traditional gravity concentrators due to the volume of water required. Using Gekko’s new Wolff BCC technology we have been able to install the unit using process water enabling us to improve recovery and reduce operating costs.” Said Dylan Morgan, Processing Manager, Kaiser Reef.
Sandy Gray is appreciative of the support of Kaiser Reef, “It has been fantastic that Kaiser Reef’s vision and management focus has allowed us to install new technology into their circuit. We appreciate the support that Kaiser Reef has shown Gekko that has allowed us to take the new Wolff technology to a new level so that it is now market ready. We’re looking forward to witnessing its impact in the mining industry.”
