Development of Electrostatic Separation Models for the Mineral Sands Industry
Industry-sponsored research at the Julius Kruttschnitt Mineral Research Centre has produced models of high tension roll and electrostatic plate separators operating in mineral sands dry plants. The behaviour of mineral species has been characterised under a wide variety of operating conditions by extensive plant machine sampling and laboratory measurements. The effect of operating conditions on separator performance has been quantified by monitoring changes in the weight distribution of mineral species along the product splitter axis. The response of each mineral species has been modelled on a size-by-size basis using an average surface charge decay time and a variation in its surface properties. The models incorporate changes in machine, mineral and ambient conditions on the separation and predict all product flows, assays and size distributions. This paper outlines the structure of the models. These models are being implemented in JKSimSand, an user-friendly simulation software Package.
