Impact of recycled and low quality process water on sustainable mineral processing practices. Water is in short supply and needs to be considered as a 'key reagent'. The quality of this reagent can vary widely. For a sustainable mineral processing practice, the use of recycled or low quality/saline process water will be essential for a plant to operate in the future. The major benefit is recognition that significant recycle of process water for flotation is achievable if simple water quality con ....Impact of recycled and low quality process water on sustainable mineral processing practices. Water is in short supply and needs to be considered as a 'key reagent'. The quality of this reagent can vary widely. For a sustainable mineral processing practice, the use of recycled or low quality/saline process water will be essential for a plant to operate in the future. The major benefit is recognition that significant recycle of process water for flotation is achievable if simple water quality control and management practices are implemented. In addition, a better understanding and control of water quality in recycled/saline process water may lead to improved flotation stability and performance, and reduced reagent consumption.Read moreRead less
Mineral Flotation - Integrating Science and Practice. Froth flotation is one of the most important processes in the recovery of valuable minerals from ores. This project aims to achieve a quantum improvement in the understanding of flotation, delivered as a computer model that will predict flotation response from measurable particle properties such as size, mineral composition and hydrophobicity. Providing the scientific foundation for the current practice of flotation, it will also allow floa ....Mineral Flotation - Integrating Science and Practice. Froth flotation is one of the most important processes in the recovery of valuable minerals from ores. This project aims to achieve a quantum improvement in the understanding of flotation, delivered as a computer model that will predict flotation response from measurable particle properties such as size, mineral composition and hydrophobicity. Providing the scientific foundation for the current practice of flotation, it will also allow floatability to be predicted when regrinding, oxidation or reagent addition occurs, which is beyond the scope of any current modelling approach. The model will be validated on full-scale flotation plants in Australian mineral processing operations.Read moreRead less
Adsorption and recovery of gold thiosulfate using nanoporous carbon. The gold industry is a major export earner for both Australia and the United States. This collaborative project aims to develop an environmentally acceptable, cost effective process for the recovery of gold from thiosulfate leachate. Development of this process will remove one of the barriers to the acceptance of thiosulfate leaching over conventional cyanide extraction, leading to substantial benefits to the gold industry and ....Adsorption and recovery of gold thiosulfate using nanoporous carbon. The gold industry is a major export earner for both Australia and the United States. This collaborative project aims to develop an environmentally acceptable, cost effective process for the recovery of gold from thiosulfate leachate. Development of this process will remove one of the barriers to the acceptance of thiosulfate leaching over conventional cyanide extraction, leading to substantial benefits to the gold industry and the environment. A successful outcome in the research project would also lead to export earnings resulting from technology transfer and an enhanced reputation for high quality research.Read moreRead less
