Abstract:
The grinding is the last stage of comminution in a mineral processing plant, responsible for reducing particles in size by mechanisms of fragmentation, impact, compression, and shear. Moreover, it is one of the stages that requires greater focus due to the more energy-consuming and major investments requirements. The grinding is considered very important for the mineral concentration process development because, when the product does not meet the specifications, grinding generates very fine products that means a significant loss and changes in further sequential steps. This work aims to optimize the ball mill in the plant 47 of Anglo American Phosphate Catalao-GO Company through simulations using the Moly-Cop optimization tools, and thereby improving energy consumption and grinding results. From real data supplied by company, the parameters of breakage and selection functions were obtained using the Moly-Cop Tools and then the mill were simulated and optimized. Simulations were performed ranging factors such as feed size distribution, critical velocity, filling rate, and ball size. The simulations results indicate a considerable decrease of 0.86 % in Wio value, changing the feeding charge from 900 to 925 t/h.
