Around 60 percent of Indonesia's total coal reserves consists of the cheaper lower quality (sub-bituminous) coal that contains less than 6100 cal/gram. There are numerous smaller pockets of coal reserves on the islands of Sumatra, Java, Kalimantan, Sulawesi and Papua but the three largest regions of Indonesian coal resources are: 1. South ...

The specific gravity of coal is the ratio of the density of coal to that of a reference substance (Usually water). This information can be used to tell whether coal will float (or sink) if dropped in water (Buoyancy). Formula SG = ρcoal / ρwater Note: Both densities need to be in the same unit as they will cancel each other and produce SG.
It was documented that coal specific gravity (S.G) can be used to have an indirect estimation for the tonnage of productions. Since S.G varies based on coal rank, various coal ranks have different conversion factors (Wood et al. 1983). Moreover, S.G is a critical factor for the selection of processing methods in coal washery plants.
Relative coal density is measured as specific gravity. Specific gravity is the ratio of the mass of an object (solid or liquid) to the mass of an equal volume of water at 4°C. For reference, the specific gravity of water is 1. Materials with specific gravities of less than 1 float in water. Specific gravities that are greater than 1 sink in water.
the country. Thus, techniques that are not typically used for coal production assessments (indirect methods), can be considered as an initial step for the development (Doebrich et al. 2006; Hare et al. 2008, 2008; Tewalt et al. 2010; Wnuk 2016). It was documented that coal specific gravity (S.G) can be used to have an indirect estimation for the

Sep 19, 2019The specific gravity of coal is important during coal cleaning because many of the common mineral impurities in coal have much higher specific gravity (density) than coal. For example, the specific gravity of pyrite (fool's gold), a common impurity in coal, and the main source of sulfur in coal, is 4.9 to 5.2. Contact
It is defined as the specific gravity at which 25% of the feed reports to clean coal (D25), minus the specific gravity at which 75% reports to clean coal (D75), all divided by 2, or: Ep = (D25 - D75)/ 2. A low Ep (.02) indicates a very precise separation, …

Specific gravity of bituminous coal = 1.32 1 ft³ of water = 62.6 lb 1 acre = 43,560 ft² 1 ton = 2,000 lb (1.32 × 62.6 lb × 43,560 ft2) / 2,000 lb/ton = 1,799.72 tons/acre-ft, which is rounded off to 1,800 tons/ acre-ft. Because specific gravity varies with rank, different ranks of coal have different conversion factors.
