A technology was developed for producing in a plasma reactor glass microspheres using the ferruginous quartzite tailings of the Kursk Magnetic Anomaly [KMA]. The predictable effects of the plasma-forming argon-gas flow rate and the plasma reactor power on the fractional composition were determined. It is shown that on increasing the plasma-forming gas flow rate …

Similarly a large extent of blue dust also does not require beneficiation and may directly be used for sinter or pellet making after proper screening. Other ores like flaky, lateritic and goethite ores due to presence of low iron, high alumina and high phosphorus contents, require proper beneficiation.

The results of investigations have shown that the dressability of the ores depends markedly on their textural-structural characteristics. As a result of structural differences, the optimal preparation conditions of the ores are inappropriate; this is the basis for recommending separate reprocessing of ores with markedly different material compositions.The mineral composition of the ores has …
