Modelling and Simulation of Slurry Phosphate Thickening

This paper proposes a simulation model established according to sedimentation process basis of high rate slurry thickener using modified Kynch flux theory and empirical formulas. A numerical simulation of the model has been developed using LABVIEW software in order to evaluate and predict the performance of sedimentation process in thickeners. Numerical solution of partial differential equations (PDE), which describe the model, is the result of resolving a selected numerical scheme using space-time discretization analysis, where the inputs are design/operation parameters, and ore settling characteristics. This study offers a convenient simulation system platform for both batch and continuous thickening, which can be used as a forecasting tool to identify thickener output operating conditions.
