The solarthermal beneficiation of IO2 entails the higher dry iron ore production relative to IO1 through the entire range of heat supplied. This is attributed to IO2 having a lower level of moisture content, which leads to lower solar energy input for water evaporation per tonne of inlet iron ore as compared to IO1.

Abstract. Dry beneficiation of fine coal was investigated using air fluidization in a vibrating air table. A systematic study based on a response surface method of experimentation revealed the features of separation. The ash content of the − mm coal feed was reduced from % to % with % mass yield of the clean coal.
