Lee, in Encyclopedia of Materials: Science and Technology, 2001 (b) Ferrochrome–silicon Ferrochrome –silicon is another chromium ferroalloy directly produced from chromite ores by carbothermic reduction in submerged arc furnace. The chromium content ranges from 34 to 42%, that of silicon …
With the increasing decline in ore quality and the increasing demand for high-quality raw materials, such magnetic separation technologies with higher separation performance are inevitably required by industry, and they include the scaling-up of current magnetic separators to meet the demand for larger-scale and lower-cost exploitation of low ...
The type and volume of metal contamination should be considered when choosing a magnetic separator. If you're dealing with larger pieces of tramp metal like nuts, bolts, or screws, then a magnetic separator designed for this type of contamination could be slightly different than a magnetic separator that targets fine metal particles, such as ...
In a Dense Media Separation (DMS)/ Heavy Media Separation( HMS) plant, powdered ferrosilicon (an alloy of iron and silicone) is suspended in water to form a fluid near the density of diamond (3.52 g/cm3), to which the diamond-bearing material is added to begin the separation process of the heavier minerals from the lighter material.
As the chromite sample contains huge quantities of iron minerals as a gangue, magnetic separator can be utilised for the separation of iron bearing minerals fro m the chro mite. The magnetic separation was carried out in a high intensity induced roll magnetic separator wh ich is of dry high intensity type.
