• TECHNICAL NOTES 8 GRINDING R. P. King

    the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. Power drawn by ball, semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure Ad this can be used to establish the essential features of a model for mill power.

     · They also compared autogenous and conventional grinding using flotation feeds of the same fineness and found improved chalcopyrite recoveries following autogenous milling. They claimed that increased chalcopyrite recovery was in part due to improved liberation caused by the selective grinding of exposed soft minerals from hard ones by the irregularlyshaped lowdensity grinding media (pebbles ...

  • SAG Mill Grinding Circuit Design

     · These mills typically grind ROM ore in a single stage. A large example of such a mill was converted from a singlestage milling appliion to a semi autogenous ballmillcrushing circuit, and the appliion is well described. This refers to highaspect AG/SAG mills.

  • Processing

     · Every 24 hours, around 180,000 tonnes of ore are fed into the six milling lines' autogenous grinding mills (AG mills), these are the largest grinding mills in the world. Each mill measures about 12 metres in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart.

  • Geometallurgy

    Geometallurgy relates to the practice of combining geology or geostatistics with metallurgy, or, more specifically, extractive metallurgy, to create a spatially or geologically based predictive model for mineral processing plants. It is used in the hard rock mining industry for risk management and mitigation during mineral processing plant design.

  • MEI's Barry Wills: Is the Autogenous Mill a Cornish invention?

     · An AG mill is a tumbling mill that uses the ore itself as grinding media. The ore must contain sufficient competent pieces to act as grinding media and preferably be high specific gravity which, for example, favors AG milling of iron ores and early deployment of AG mills can be attributed primarily to a need in the iron ore industry to economically process large quantities of ore in the late ...
