Mineral Evaluation of Black Shale of Chimiari region of Khyber Pakthunkhawa, Pakistan by Size Analysis
نویسندگان
چکیده
The black shale of Chimiari region of Khyber Pakthunkhawa Pakistan is sieved for its mineral evaluation of various fractions. Disc Pulverizer made by Mine and Smelter Supply Co. Denver USA used for grinding and Tyler series for sieving to get the required range of fractions. Study showed a gradual decrease in concentration of S iO2, Al2O3, K2O, V2O5 and TiO2 from higher fraction size to lower fraction size and similarly a gradual increase in concentrations of Fe 2O3, CaO, SO3, and MnO2 from higher fractional size to lower fraction size. MgO attained more or less the same value in all fractions. Using water as suspension media and further microscopic studies reveals that 83.65 % of suspended particles are equal to or less than 10.53 μm size. Index Term-black shale, chimiari, minerals, sizing, upgradation.
