Effects of the chemical composition of coal tar pitch on dimensional changes during graphitization
Coal can be converted to different chemical products through processes such destructive distillation. The destructive distillation of coal yields coke as the main product with byproducts such as coal tar pitch (CTP). CTP ...
Liberation of chromium from ferrochrome waste materials utilising aqueous ozonation and the advanced oxidation process
(North-West University, 2014)
During ferrochrome (FeCr) production, three types of generic chromium (Cr) containing wastes are generated, i.e. slag, bag filter dust (BFD) and venturi sludge. The loss of these Cr units contributes significantly to the ...
Spatial and temporal assessment of atmospheric organic carbon and black carbon concentrations at South African DEBITS sites
The baseline of uncertainty in aerosol radiative forcing is large and depends on aerosol characteristics (e.g. size and composition), which can vary significantly on a regional scale. Sources (natural and anthropogenic) ...
Comparison of physical properties of oxidative sintered pellets produced with UG2 or metallurgical grade South African chromite : a case study
The Bushveld Igneous Complex (BIC) in South Africa holds approximately three quarters of the world’s viable chromite ore deposits. Most chromite is used for the production of ferrochromium (FeCr), which is a relatively ...
