quantitative measurement of copper mineralogy using

2007-12-1 · The instrument has been developed to provide rapid on-line determination of phase concentration. The on-line measurement of copper mineral phase would be of considerable assistance to the mineralogist or process engineer for process optimisation. Ultimately, the underlying method may be applied in ore streams on conveyors or batch samples
