Coal Structure and properties of coal Britannica
Coal Coal Structure and properties of coal: The plant material from which coal is derived is composed of a complex mixture of organic compounds, including cellulose, lignin, fats, waxes, and tannins As peat formation and coalification proceed, these compounds, which have more or less open structures, are broken down, and new compounds—primarily aromatic (benzenelike) and hydroaromatic The raw coal properties as described in Table 32 and the operational efficiency of the separator determine the effectiveness of separation The valuable carbonaceous material can be separated from mineral matter with the correct type of coal preparation Among the different properties, size, density and surface wettability play a key role in Coal Property an overview ScienceDirect Topics (Keywords: coal, mechanical separation, macais) Classically, scientists strive to reduce a system of components to their individual constituents, then study the properties of the individual constituents and infer the properties of the whole on the basis of this simpler material Coal with its component macais is an example of such a systemSeparation of coal macerals ScienceDirect

Of the dry coal separation methods, ai r densemedium (magnetic pearls from coal ash) fluidized beds have been used to separate 50~6mm coal efficiently Magnetically stabilized fluidized However, surface oxidation occurring on metabituminous coal after mining can reduce its natural hydrophobic properties due to the formation of oxygenated functional groups on coal surfaces , Froth flotation is a widely used separation method for fine coal cleaning and its upgrading based on the differences in surface hydrophobicity of coal Surface properties of aged coal and their effects on The Magnetic Fraction of Coal Fly Ash: Its Separation, Properties, and Utilization M J MURTHA and G BURNET Ames Laboratory USDOE and Department of Chemical Engineering and Nuclear Engineering Iowa State University, Ames, Iowa 50011The Magnetic Fraction of Coal Fly Ash: Its Separation
