Chemistry of uranium extraction - studies on the dissolution of uranium ores in a complex solution matrix. Olympic Dam is the world's largest uranium deposit. With a planned massive expansion of the mine's operations, it could generate more than $10b per year. The mineral ores found there, however, are highly complex and poorly understood. This project will investigate and determine the detailed characteristics and chemistry of the mineral ore and offer process improvements that will increase th ....Chemistry of uranium extraction - studies on the dissolution of uranium ores in a complex solution matrix. Olympic Dam is the world's largest uranium deposit. With a planned massive expansion of the mine's operations, it could generate more than $10b per year. The mineral ores found there, however, are highly complex and poorly understood. This project will investigate and determine the detailed characteristics and chemistry of the mineral ore and offer process improvements that will increase the productivity and improve the economics of extraction of the ore. This project will also address the serious deficiency of researchers in this field by creating a sustainable skills development program in mineral extraction and separation technology.Read moreRead less
Enhanced metal recovery from a modified Caron leach of mixed nickel-cobalt intermediate concentrate. Nickel metal production from lateritic deposits involves dissolution in acid followed by purification and selective alkaline precipitation of the nickel and cobalt as hydroxide phase. Hydroxides from several plants are transported to a central refinery where the hydroxide is redissolved in ammoniacal solutions and nickel and cobalt are separated and reduced to metal.

Hydroxides from several plants are transported to a central refinery where the hydroxide is redissolved in ammoniacal solutions and nickel and cobalt are separated and reduced to metal.
This project will examine the effect of preparation conditions and aging of the hydroxide precipitate on the refining process.

Practical Application of Filtration Theory to the Minerals Industry. The project aims to provide a quantitative basis for the selection, design, operation and maintenance of filter devices in the minerals industry. This will be achieved through characterisation of materials to be filtered by developing a model of the true role of the membrane in filtration. Experimental parameters will be input to first principles filtration models. This will reduce the incidence of poor operational outcomes ....Practical Application of Filtration Theory to the Minerals Industry. The project aims to provide a quantitative basis for the selection, design, operation and maintenance of filter devices in the minerals industry. This will be achieved through characterisation of materials to be filtered by developing a model of the true role of the membrane in filtration. Experimental parameters will be input to first principles filtration models. This will reduce the incidence of poor operational outcomes for filter presses and provide a sound basis for the maintenance of filter cloths and membranes.Read moreRead less
