CR Separation of FAT: recovery of chrome ore sand
Solutions: The magnetic characteristics of the chromite sand are used to separate the sand mixture. A strong- field magnet separates the chromite sand from the silica sand and the waste fraction. In a downstream stage, the separation process is supported by a fluidising unit and the result will be further optimised.

Chromite sand separation - GIESSEREILEXIKON.COM
The magnetic separator has two consecutive separation steps. In the first step, magnetic metal parts are removed, while in the second step, the chromite sand is separated from the quartz sand with a stronger magnet. If necessary, a third step with a magnet with an even stronger magnetic field can be included in order to reclaim almost 100 % ...

Effect of basicity on beneficiated chromite sand smelting process
2018.5.15 The process followed by another magnetic separation, thus the Cr/Fe ratio was increased from 0.9 to 1.6. The reduction process used coconut shell charcoal as reductant and limestone as an additive. The beneficiated sand chromite was briquette using bentonite as a binder in 2 wt.% before it was smelted in a submerged electric arc

Chromite Separation Case Study by Omega Foundry Machinery
2013.8.29 As can be seen from the above XRF results, the seperated chromite sand contains less than 0.5% silica contamination and therefore is perfect for re-use at the mixer. As a general side effect from the casting process, the chromite sand tends to see most of the heat from the molten metal and so is also naturally thermally reclaimed.

2020.9.19 However, when this separation is not accurate, too high fraction of SiO 2 in chromite sand worsens its fire resistance (maximum SiO 2 content should be 1%). Chromite sand indicates a high resistance to influences of metal oxides and slags. It is weakly wetted by liquid casting alloys, due to which a penetration effect is limited to a
