Particle size, also called grain size, means the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be used for other granular materials. φ scale Size range (metric) Size range (approx. inches) Aggregate name (Wentworth Class) Other names < −8 > 256 mm
Experimental investigation for removal of mineral matter from Indian coal by using three different solvents such as Tetrahydrofuran, 1,4 Dioxane and Diethyl ether. Comparative study on reduction of ash content of Indian coals having different average particle sizes (0.126mm,0.258mm and 0.403mm) using different solvents reveals that ...
The highest peak in unimodal distribution at all sampling sites also occurred within this particle size range. The next relative abundance was found with the particle size range from 0.1 to 1.0 μm associated with the particles in the accumulation mode. The multimodal distribution also occurred in the particle size range from 0.1 to 10.0 μm.
In a latter investigation [], the same Kusunda coal was crushed to a nominal size of −15 mm.Under the specified experimental conditions (Table 2) for the fines thus generated, about 27% yield could be obtained at 17% ash at a flotation time of only 30 s.More than 40% yield could be obtained at about 18% ash, time requirement being more than 60 s.

Coal washery wastes comprise tailings finer than 0.5 to 0.1 mm depending on the sophistication of the washery, and coarse reject, typically finer than 50 mm. Subaerial disposal of coal tailings slurry at about 30% solids by mass results in the formation of a delta with an average slope of about 1 in 100, representing one extreme.
Coal Centre – Coal sampling and analysis standards 4 Abstract Each year, billions of tonnes of coal are traded in regional and international market for use in power generation, steel and cement making, and many other purposes. In commercial operations, the price of coal
The maximal methane flow rate of 1.9 m 3 /min matches with size 0–25 mm with the maximal total area of 18.56 m 2 (Fig. 1c). The total area of coal particles of all sizes in this same is 22.7 m 2.The methane flow rate from other sizes is lower: 0.040, 0.011 and 0.0003 m 3 /min, respectively, for the sizes of 25–50, 50–100 and 100–150 mm. The total methane flow rate from all sizes in ...
Background. Platinum group elements (PGE), in particular platinum (Pt), palladium (Pd), and rhodium (Rh), are few of the least abundant elements in the Earth's continental crust, with estimated concentrations of 0.4–0.06 ppb (Wedepohl 1995).These metals and their compounds are highly valued by chemical, food and pharmaceutical industries for use as catalysts in a wide range of reactions ...

A constant difference of isotherm with coal particle size results is also observed (Busch et al., 2004). Busch et al. (2004) found that obvious variations existed in the isotherms for different particle size coal samples, but no specific trend was claimed in terms of shape or maximum sorption capacity.

Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.
