The Importance of Primary Crushing in Mill Feed Size ...

As part of its investigation into run-of-mine ore fragmentation, Highland Valley Copper discovered the role of primary crushing in the optimisation of mill feed size. Image analysis methods were used to quality the effect of feed size on mill throughput and showed the in-pit crushers to be an integral step in the preparation of feed for the AG ...

Common Basic Formulas for Mineral Processing

Mar 20, 2016  As used in these formulas the specific gravity of the ore is obtained simply by weighing a liter of mill pulp, then drying and weighing the ore. With these two weights formula (2) may be used to obtain K, and then formula (1) to convert to S, the specific gravity. A volumetric flask of one liter capacity provides the necessary accuracy.
