The Development of Process Flow Sheet for Froth Flotation Method of Coal Deposit in The Case of Yayo Area, South-Western Ethiopia
Abstract:
Coal is a mixture of organic and inorganic materials and has the ability to burn easily. The objective of this research was to develop a froth flotation flow sheet for the Yayo coal deposit using METSIM simulation software. In this study, the flotation flow sheet for the Yayo coal deposit was created by conducting proximate analysis value and ultimate analysis value. The particle sizes examined were 500μm, 250μm, 125μm, and 63 μm. Based on the particle size distribution, it was found that the 125μm particle size was most suitable for producing high- quality coal with a high percentage yield, as determined by the METSIM simulation software. The proximate analysis values obtained through the simulation software indicated that the moisture content of the coal was 21.25%, the volatile matter content was 22.3%, and the ash content was 6.42%. The average values of the ultimate analysis revealed that the coal contained 62.022% carbon, 4.558% hydrogen, 27.1653% oxygen, and 12.87% sulfur, as determined by the METSIM software simulation. Moreover, the carbon content result obtained from the METSIM simulation software was 79.49%, indicating that the coal in the study area is classified as bituminous coal, which is known for its relatively high carbon content.
