  • Chemical Beneficiation of High-Ash Indian Noncoking Coal

    2019-8-7 · Coal mined from the Talcher region of Odisha, India is known to be high-ash, surface-oxidized, and noncoking in nature. It is quite challenging to beneficiate such low-grade coal by physical or physicochemical processes due to its oxidized nature and the presence of complex ash forming mineral matter in its matrix. Chemical beneficiation is one of the alternative process to such problemsBeneficiation of oil shale by froth flotation SpringerLink,2018-7-21 · The optimal flotation performance occurred for a pulp concentration of 50 g/L, a collector dosage of 1000 g/t, a frother dosage of 300 g/t, an agitation speed of 1900 rpm, and an aeration rate of 160 L/h. Froth flotation is a mature method and is widely used, and thus, it can be used to improve the industrial production of oil shale.
