    Apr 05 2017 From 85 to 95 percent of the ore usually can be recovered by shrinkage stoping with dilution of 5 or 10 to 25 percent except where some other method would be better suited to the conditions. Sometimes dilution runs 30 percent or more but in most such instances cut-and-fill or some other method probably should be employed.

  • Efficient Enrichment Of Iron Concentrate From Iron

    Mar 13 2020 The iron concentrate grade and iron recovery were relatively low in a shorter roasting time because the reduction degree of minerals by carbon monoxide was not enough. The prolongation of reaction time would increase the reducibility of iron ore and then heighten the index of magnetic separation concentrate.

  • Twostep Flotation Recovery Of Iron Concentrate From

    The flotation recovery of pure hematite siderite and quartz in the oleate-starch-CaCl 2 system is significantly different when the slurry pH varies from 4 to 12. A novel two-step flotation process was developed for the separation of iron concentrate from Donganshan carbonaceous iron ore through which the siderite concentrate is first recovered and the high quality hematite concentrates with relative high

  • Iron Ore Mining Artifacts

    The typical magnetite iron ore concentrate has less than 0.1 phosphorus 3-7 silica and less than 3 aluminum. The grain size of the magnetite and its degree of comingling with the silica groundmass determine the grind size to which the rock must be reduced to enable efficient magnetic separation to provide a high purity magnetite concentrate.
