The direct liquefaction of South African coal fine discards and their density separated (float) fractions were carried out under moderate conditions in a laboratory autoclave. The liquefaction temperature ranged between 380 and 420 °C, using tetralin as a solvent and an initial nitrogen gas pressure of 3 MPa.

· Coal sales where 40% higher than PGM sales in January 2019, 75% higher than Gold sales in Janaury 2019 and it was 268% higher than the sales achieved by Iron Ore miners in South Africa. Coal truly is South Africa''s "Black Gold" and its taking the shine away from all of South Africa''s other commodities and minerals.
· The three types of coal are anthracite coal, bituminous coal and lignite coal. Anthracite coal has a bulk density of 50 to 58 pounds per cubic feet, or 800 to 929 kilograms per cubic meter. It is a mature coal and is very hard and shiny. Bituminous coal has a bulk density of 42 to 57 pounds per cubic feet, or 673 to 913 kilograms per cubic meter.

· Living between two coal mines and a landfill in Middelburg, South Africa, he and his family breathed some of the country''s most polluted air. When Mnguni''s son developed symptoms of asthma, a doctor recommended that the family move to a different part of town. Now living about six miles from the mines, the 14-year-old is doing better.
specific South African coal. According to Pinheiro (1999), the ash values for South African coals range between 6.8 wt. % and 42.7 wt. % (air-dry basis). As seen in Table 4.3, the ash value of the washed coal sample is 12.6 wt. %, which is a relatively low ash content compared to South African ROM coals.

Coal density is among the important parameters for reservoir engineering purposes and is inserted as an input property in simulation studies. Coal density is typically less than that of conventional reservoirs and differs from seam to seam based on the given coal rank and purity .The bulk density of a coal consists of the matrix and the void space, with the latter being expectedly filled ...

· Coal and bituminous coal made up 6.4% of South Africa''s total exports for 2018, with Gold and Platinum and other precious metals making up 5.75% of South Africa''s total exports during 2018 Top 5 imports into South Africa during 2018: Crude Oil: R 144 954 759 047
Results for the separates allow prediction of Hg, trace elements, and ash yields expected in specific South African coal products. These range from 0.06 ppm Hg and an ash yield of 11.5% ash for the export fraction to 0.47 ppm Hg and an ash yield of 60.9% for the discard (stone) fraction (dry basis).
Hydro-Anthracite can be used alone for water filtration or with various sizes of sand in dual-media filters. Its unique shape and density allow it to filter more efficiently, making it the perfect media for the filtration of drinking water, processed water, pool water, wastewater, industrial water, and municipal water.

· Anthracite is coal, which is found in minimal amounts in nature, is the type of coal with the highest heat quality when compared to other coal types. Only %5 of the world''s total coal is Anthracite. South Africa, the USA, China, Russia, Ukraine, North Korea, Vietnam, UK, Australia, and Canada are the countries where Anthracite is mined.
BULK DENSITY The bulk density of coal particles in a sample is the mass of the coal divided by the volume that the coal particles occupy. Tests are done in either small or large container formats. Un-compacted bulk density is not an intrinsic property of a coal pile as it can change depending on how the coal is handled, how much
