Over the last 3 years, South Africa reserves of anthracite and bituminous coal remained stable at around 9,893 million tons. An estimate of coal reserves, based on a demonstrated reserve base, adjusted for assumed accessibility and recovery factors, and does not include any specific economic feasibility criteria.
2.1. Origin of coal samples. The four run-of-mine bituminous coal samples examined in this investigation were collected from actively mined underground coal seams within the Highveld, Witbank, and Tshipise-Pafuri coalfields of South Africa. The coal samples are identified henceforth as coals: DEN, FOZ, OGS and TKD.

Modern coal-quality data and geologic field observations are interpreted in terms of the coal geology in a small area near Pocahontas, Va. Detailed chemical analyses and physical-property determinations of 12 channel-coal samples (reported on whole-coal and laboratory ash basis) indicate that the coals are mostly of high coking quality, low
Mar 04, 2019· Fourteen coal-shale samples collected from four different coal mines in Witbank Coalfield, South Africa, were experimentally investigated. The influence of coal-shale intrinsic properties and spontaneous combustion liability indices (determined by the Wits-Ehac Index and the Wits-CT Index) were established.

Oct 21, 2019· Bituminous coal combustion releases more pollution into the air than sub-bituminous coal combustion, but due to its greater heat content, less of the fuel is required to produce electricity. As such, bituminous and sub-bituminous coals produce approximately the same amount of pollution per kilowatt of electricity generated.
This research data gives insight into the sorption properties of typical South African bituminous coal. The data provided can be used by other researcher as a benchmark for future work.
In this paper, we report the CO 2, CH 4 and N 2 sorption properties of four bituminous coals from underground coal seams of South Africa at supercritical conditions, up to 16.4 MPa at 55 °C. Different isotherm models were studied and coal and gaseous adsorbate properties impacting the sorption properties of these coals were examined.

The abundance of coal combined with lack of natural gas resources in China is a strong inducement for the coal to chemicals industry there. Similarly, has built and operated coal-to-chemicals facilities in South Africa. Coal to chemical processes require substantial quantities of water.
Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen or asphalt. It is of higher quality than lignite coal but of poorer quality than anthracite. Formation is usually the result of high pressure being exerted on lignite.
Mar 17, 2015· {{#badges: CoalSwarm|Navbar-SouthAfricaCoal}}South Africa is the fifth largest hard coal producer in the world and a major exporter of coal into the world market. It is also heavily dependent on coal for power generation and is aiming to rapidly expand its coal-based generation capacity.
Mineralogy and Geochemistry of Sub-Bituminous Coal and Its Combustion Products from Mpumalanga Province, South Africa 51 All of the water is lost during the high-temperature ashing. Pyrite is the main species of sulfur oxidation in the coal samples studied. Pyrite occurs as typical syngenetic framboidal,
Coal mining's advent in South Africa can best be traced to the start of gold mining in the late 19 th century, particularly on the Witwatersrand, with the first coal in appreciable tonnages being extracted on the Highveld coal field close to the nascent Witwatersrand gold mines. However, demand began to grow, slowly at first but then ...
