MATHEMATICAL MODELS FOR UNIT OPERATIONS IN A TWO-STAGE FLOTATION CIRCUIT FOR PHOSPHORITE ORES

On the basis of industrial test data obtained from Wangji Phosphorite Processing Plant, mathematical models for unit operations in a two-stage flotation circuit for Phosphouite ores are established by using regression analysis. Statistical tests show that the models fit in with the data. The results from the models can accurately predict separating performance of the tnt operations. The models can be used to determine the flotation agent system and direct the industrial operation.
