Abstract: CEET, an acronym for Comminution Economic Evaluation Tool, was jointly developed by MinnovEX Technologies Inc. and 13 major mining companies for the purpose of designing and predicting the performance of grinding circuits. It fundamentally differs from other methods by using as its' data set a geostatistically significant population of hardness data distributed across the mine block model. In addition to power selection and shell sizing for multiple circuit options, CEET also outputs tons per hour, P₈₀ and operating cost on every mining block in the mine block model.

Key words: CEET, SAG/AG, SPI, BWI, Mine block model, Grinding circuit, Specific energy
