Energies Special Issue : Low-Grade Coal Beneficiation

Thus, there is growing importance of beneficiation of low-grade (low-quality) coals considering the declining of high-grade coal around the world. Approximately one-third of the coal produced in the world, except for China, is low-grade. The low-quality coals cannot be used directly in industries due to it’s poor physico-chemical properties.

Beneficiation of a Low Rank Coal to Produce High Quality

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.
