The influence of the roof and floor geological structures on the ash composition produced from coal at UCG temperatures

Uwaoma, R.C.; Strydom, C.A.; Matjie, R.H.; Bunt, J.R.; Van Dyk, J.C. (Taylor & Francis, 2020)

The mineralogy of the ash and slag formed at typical UCG temperatures were investigated using a bituminous coal from the Theunissen UCG site in the Free State province of South Africa. The ash and slag samples were produced ...
Metals and metalloids in corals from the Western Indian Ocean

Van der Schyff, Veronica (North-West University (South Africa), Potchefstroom Campus, 2018)

Coral reefs are one of the most species diverse biomes on earth. One of the many dangers that coral reefs face because of anthropogenic activities is the accumulation of metals and metalloids in skeleton and tissues of the ...
Water leaching of inorganic species from coal ash and slag generated at typical Underground Coal Gasification (UCG) temperatures

Uwaoma, Romanus Chinonso (North-West University (South Africa), Potchefstroom Campus, 2017)

Underground coal gasification (UCG) is a better and more environmentally friendly way of gasifiying coal, using coal seams that are not economically viable to mine or coal seams that are deep underground. This technology ...
