Jun 28, 2021 A process was developed for the beneficiation of a low-rank coal containing relatively high ash (25.97%) and sulphur (5.78%) content. The low-rank sub-bituminous coal of Makerwal Area, Surghar Range, Punjab Province, Pakistan was cleaned by froth flotation technology to get high quality clean coal for commercial applications.

The efficiency of iron recovery is 90-95% (as against 70-75% in the conventional beneficiation plants) the left-over Fe in the tailings is only 10-15% (as against 35-45% in the conventional beneficiation plants). In the process, low grade iron ores are dry-ground, preferably to their liberation size passed through a fluidized bed roaster.
