An evaluation of novel aluminosilicate materials based on modified kaolins for environmental applications. We have shown that simple and inexpensive modification of kaolin produces materials that adsorb large amounts of ammonium (N) and phosphate (P). We intend to evaluate and develop these materials for water treatment, so as to reduce N, P inputs into rivers and wetlands. The materials can then be used as fertilisers. Similarly addition of the materials to sandy soils to reduce leaching losses ....An evaluation of novel aluminosilicate materials based on modified kaolins for environmental applications. We have shown that simple and inexpensive modification of kaolin produces materials that adsorb large amounts of ammonium (N) and phosphate (P). We intend to evaluate and develop these materials for water treatment, so as to reduce N, P inputs into rivers and wetlands. The materials can then be used as fertilisers. Similarly addition of the materials to sandy soils to reduce leaching losses of N, P from fertilisers will be investigated. The major outcome of this research will be effective and inexpensive procedures for reducing eutrophication due to N, P from waste water and fertilisers.Read moreRead less
Experimental constraints on Platinum-Group Element geochemistry: developing lithogeochemical exploration tools for nickel-sulfides in mafic and ultramafic systems. Nickel contributes approximately $2 billion per year to Australia's export income. Currently 80% of that is coming from sulfide deposits, which are expected to be exhausted within thirty years barring significant new discoveries. Discovery rates have been declining for two decades, as the 'easy' targets have been found, despite a broa ....Experimental constraints on Platinum-Group Element geochemistry: developing lithogeochemical exploration tools for nickel-sulfides in mafic and ultramafic systems. Nickel contributes approximately $2 billion per year to Australia's export income. Currently 80% of that is coming from sulfide deposits, which are expected to be exhausted within thirty years barring significant new discoveries. Discovery rates have been declining for two decades, as the 'easy' targets have been found, despite a broad increase in nickel exploration expenditure to current levels of around $50 million per year. There is a pressing need for new data sets and techniques to allow industry to target new discoveries based on limited drill sampling of potential host rocks. This project forms part of a broader program to harness the igneous geochemistry of the platinum group elements as a powerful pathfinder in nickel exploration.Read moreRead less
