Ultra-Dynamics have recently developed a system which can rapidly determine the magnetic fractions of samples of materials. The system developed includes the MAGNASAT technology together with a mathematical algorithm developed to determine the percentage of the feed material at each level of magnetic susceptibility. A finely crushed sample of material is passed through a funnel which allows the analysis of the sample particle by particle with the result displayed on a PC in graphical format.
Application:
The measurement of magnetic susceptibility is widely used in the mineral sands industry particularly in processing titanium minerals. The expected mineral recoveries are assessed by performing laboratory magnetic separations of representative samples to determine the distribution of magnetic components. Traditionally this has been carried out using the traditional Permroll technique which is a slow and labour intensive process performed on relatively small samples.
