A new methodology for the measurement of transition metals ions in complex, high temperature oxide systems relevant to non-ferrous metal production. Complex multi-component molten oxide phases, known commonly as slags, are used in the high temperature production and refining of metals. The slag systems of commercial interest contain transition metals species, such as, Fe2+, Fe3+. Each of these species behaves as if it were a separate chemical component. Researchers at the University of Queensla ....A new methodology for the measurement of transition metals ions in complex, high temperature oxide systems relevant to non-ferrous metal production. Complex multi-component molten oxide phases, known commonly as slags, are used in the high temperature production and refining of metals. The slag systems of commercial interest contain transition metals species, such as, Fe2+, Fe3+. Each of these species behaves as if it were a separate chemical component. Researchers at the University of Queensland have developed a new methodolgy, which enables the concentrations of these transition metal ions to be measured.
These types of measurements cannot be made with any of the techniques currently in use. The study will provide data on high temperature slags in a number of industrially and scientifically important systems. This approach will be applicable to a wide range of chemical systems in the fields of extractive metallurgy, materials science and geology; systems which could not previously be characterised.Read moreRead less
Improvements in the pyrometallurgical processing of nickel oxide and laterite ores at QNI Yabulu, North Queensland. The QNI Yabulu operation in Queensland is an important supplier of nickel and cobalt metals to the export market. The company is planning to expand the scale of the operations but is faced with two important sustainability issues. One is the recent changes to the European regulations that require very low levels of residual nickel oxide in the nickel metal product.

The QNI Yabulu operation in Queensland is an important supplier of nickel and cobalt metals to the export market. The company is planning to expand the scale of the operations but is faced with two important sustainability issues. One is the recent changes to the European regulations that require very low levels of residual nickel oxide in the nickel metal product. The second issue relates to ensuring the supply and improved recovery of nickel and cobalt from oxide-based ores. Further fundamental scientific information is required to provide improved understanding of the complex chemical reactions occurring during the high temperature treatment of these materials, and to guide improvements in product quality, recovery and process efficiencyRead moreRead less

The world's current iron and steelmaking production capacity is over 200 million tonnes annually; this is set to rapidly rise with the increasing production in China and in India. Australia is a major exporter and supplier of iron ores and coal and coke to the South East Asian region. It is in Australia's National interest to encourage improvements in these technologies not only to increase export income but also to contribute to improved environmental performance. The proposed project will assist in the development of a modified iron blast furnace, and in so doing substantially reduce the energy consumption and CO2 emissions from the process.Read moreRead less
Development of an efficient oxygen-thiosulfate process for the recovery of gold from ores. Gold is currently recovered from the ore by a cyanide leaching process.

Gold is currently recovered from the ore by a cyanide leaching process. This high risk procedure is used because there is currently no safe alternative. The research we propose to undertake will investigate a novel thiosulfate-oxygen process to dissolve gold. Successful completion of the project will identify the mechanism of the process and could lead to the replacement of the highly toxic cyanide with the non toxic thiosulfate. Thus the proposed project has the potential to substantially alter the gold recovery process, particularly in an era where environmental and public concerns exist over the use of cyanide.Read moreRead less
