Binary modelling the milling of UG2 ore

2015-5-11 · Finally, a matrix model transformation of a binary UG2 ore was developed for a basic closed ball mill-hydrocyclone circuit. The model described satisfactorily the grinding behaviour of the chromite and non-chromite separately. This model is useful for showing effects of the milling of a binary ore on the ball mill circuit output.

Grade Control | SpringerLink

Abstract. In some mining operations, one of the most important roles played by the geologist is the supervision of grade control. In an open-pit operation, this involves the sampling of blast-hole cuttings produced by down-the-hole hammer drills and the classification of bench reserves into ore, low grade or waste material, or into various metallurgical types.

Mill power draw models

Mill power draw models

2020-3-22 · Mill Power Draw Models. The mill power draw models are used to predict how much power will be consumed by a particular type of mill, mill geometry and set of mill operating conditions. This power is transferred to the ore and used to predict the throughput when combined with the specific energy consumption models.
