Dry type magnetic separation of dry grinding ore is used in water shortage area. The rich magnetite ore or poor magnet ore, which is depleted, usually uses dry magnetic separation to remove the gangue, the former gets the massive ore, and the latter gets the concentrate through the grinding magnetic separation.

GAs during the dry grinding of magnetite and suggested that Zalta™ GR20-587, Zalta™ VM1122, and sodium hydroxide can reduce energy consumption compared to dry grinding without additive (Chipakwe et al. 2020b). This current study reports the findings on the characterization of dry ground magnetite ore

First, it confirmed that grinding the ore finer resulted in improved magnetite liberation which led to improved iron and magnetite grades with the finer feed sizes. For example, with the average size of the magnetite mineral in the ore being approximately 26 µm, crushing the feed to P 80 = 30 µm resulted in higher magnetite liberation and hence, yielded the …

By adopting the magnetite dry grinding and dry separation method, the crushing grinding and the magnetic separation of the ore are reasonably matched, so that the system energy consumption is reduced, consumption of steel and water is reduced, and the environmental pollution is alleviated.Image:201510237394.GIF. ：

The grinding required for balling and to produce an acceptable product quality is essentially the same in the case of either magnetite or specular hematite concentrates. The specific surface area, as measured by Blaine permeability testing, required to produce an acceptable product is normally in the range of 1400 – 1600 cm²/gram for magnetite and 1600 …

For the depleted magnetite-rich ore or magnetite-rich ore, the gangue can generally be removed by dry magnetic separation process, and then the lump-rich ore is obtained, and then the concentrate is obtained through the grinding-magnetic separation process.

dry magnetic cobbing separation - 911 metallurgist. Nov 05, 2020 · When fine-grained magnetite is the only mineral of value and there is a minimum of dilution rock and barren material in the ore, elimination of cobbing in the crushing plant in favor of wet rougher magnetic separation in the grinding circuits should be considered.

Dry type magnetic separation of dry grinding ore is used in water shortage area. The rich magnetite ore or poor magnet ore, which is depleted, usually uses dry magnetic separation to remove the gangue, the former gets the massive ore, and the latter gets the concentrate through the grinding magnetic separation.
