Core Resources presented the second in a series of technical webinars that provide practical and innovative technical solutions for minerals processing and hydrometallurgical projects at every stage of development. The topic for the second webinar was unlocking the value of high arsenic copper projects using the Toowong Process.
The Toowong Process – Unlocking the Value from High Arsenic Copper Projects
Increasing arsenic grades in copper concentrates and precious metal concentrates is an issue of global significance. With growing environmental pressures at smelters, penalties for arsenic in copper concentrates continue to rise accompanied by lower reject limits. There is a strong incentive for miners to investigate alternative means to remove arsenic and penalty elements to valorise their ores and concentrates.
The Toowong Process is a proprietary technology that selectively removes arsenic, antimony, mercury and other penalty elements from base metal and precious metal concentrates. The product from the Toowong Process is a premium “clean” concentrate that can be marketed to conventional smelters without incurring penalty fees.
This webinar discussed the global problem of arsenic contamination in complex ores and concentrates, how the Toowong Process technology can change the way arsenic is managed in the mining industry and the economic advantages the technology brings to the business of dirty concentrates.
