OPTIMIZING COPPER–MOLYBDENUM ORE MILLING COARSENESS USING MODEL-ORIENTED CRITERIA

With a view to improving efficiency of copper–molybdenum ore processing, it is proposed to measure concentration of nonionic collecting agent in pulp water phase and to take these data into account when selecting milling and flotation modes. Based on the information on milling fineness and collector concentration in pulp water phase, the model is obtained, which relates metal recovery and flotation performance. Using the model and the economically oriented optimization target function, the optimal coarseness of copper–molybdenum milling is determined. The developed model and the optimal milling coarseness algorithm are included in the milling optimization systems applied at the processing plant of Erdenet Mining Corporation.

Keywords
