Core Resources recently hosted the second session in its technical webinar series, focusing on practical and innovative solutions for minerals processing and hydrometallurgical projects. This session addressed the challenges of treating high-arsenic copper concentrates, introducing the Toowong Process™ as a viable solution.

The increasing presence of arsenic in copper and precious metal concentrates poses significant environmental and economic challenges. Smelters are imposing stricter penalties and lower rejection thresholds for arsenic content, compelling miners to seek alternative methods for impurity removal to valorise their ores and concentrates.

The Toowong Process™ is a proprietary hydrometallurgical technology developed by Core Resources. It selectively removes arsenic, antimony, mercury, and other deleterious elements from base and precious metal concentrates. The result is a premium “clean” concentrate suitable for conventional smelters without incurring penalty fees.

This webinar delved into the global issue of arsenic contamination in complex ores and concentrates. It explored how the Toowong Process™ can revolutionise arsenic management in the mining industry and the economic benefits it offers for processing high-arsenic concentrates.

The session was presented by Lachlan MacDonald, Toowong Process Technology Manager at Core Resources. Lachlan has led the development of the Toowong Process™ through conceptual flowsheet development, pilot plant validation testing, engineering and feasibility studies, and commercialisation.

For those who missed the live session, a recording of the webinar is available here.

This webinar underscores Core Resources’ commitment to providing innovative metallurgical testing and process engineering solutions that address critical challenges in the mining industry.
