    Pdf Optimization Of Operating Parameters Of Graphite

    Flotation is a continuous process, therefore conventional tree analysis tests do not fit to determine the quantity and quality of the products. Hence, it is necessary to incorporate flotation circuits. The present study presents optimization of three stage graphite flotation circuits. Response Surface Methodology RSM is used to determine the optimum flotation conditions.
