1. Introduction. Coal has historically been a major contributor to economic growth of many countries as a key source of energy. However, the natural friability, mechanized mining, handling system and size reduction methods have led to increase in production of coal fines (Hacifazlioglu, 2012).Statistics show that over 30 billion metric tons of coal are available in the top 10 coal producing

Beneficiation Wikipedia

In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (concentrate) and a waste stream ().There are many different types of beneficiation, with each step furthering the concentration of the original ore.
