A pilot-scale test was done on the continuous type model plant, and the different operations involved are described further. Sesa-codli iron ore tailings were subjected to a laboratory-scale test.

One of the targeted markets is the upgrading of fine iron ore. STET has performed exploratory studies with several iron ores and experimental results to date have demonstrated that low-grade iron ore fines can be upgraded by means of STET tribo-electrostatic belt separator.

Influence of shear rate on separation of iron ore fines using the REFLUXTM Classifier. The REFLUX Classifier is used to perform particle separations on the basis of density utilising a set of parallel inclined channels positioned above a vertical fluidised section. In continuous mode, feed enters part way up the vertical section, while ...
