A one day workshop for geologists process mineralogists metallurgists and researchers who work in the iron ore and iron making industries Conducted by experts from CSIRO Mineral Resources registrants will gain an overview of basic ore types and advanced characterisation techniques including core
The development of automated spectral systems with the ability to scan large volume of samples has been a catalyst for the routine use of these techniques in iron ore These systems can be applied to rock hand samples drill chips diamond cores mine faces and the whole mine either for exploration processing or environmental monitoring
Iron ore is common in many mineral forms (hematite magnetite goethite limonite or siderite) and has mineral-specific analysis requirements Borate fusion with XRF analysis is an extremely robust technique for major and minor elemental analysis in complex mineralization and offers highly precise and accurate results for iron ore samples

The opportunities commonly include: methods to create better estimates improved designs tighter and more accurate plans and schedules improved mining techniques to minimise ore loss and dilution and identifying ways to increase metal recoveries during the extraction processes
The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores The oxidized ores consisting of the silicates carbonates and sulfates are treated by several methods all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate
