Effect of sodium compounds on the sintering propensity of coal-associated minerals
(Elsevier, 2015)This study focused on the chemistry involved in sintering of coal-associated minerals during combustion and inert conditions. Changes in mechanical strength were recorded with compressive strength measurements. This method ... -
Manufacturing and testing of briquettes from inertinite-rich low-grade coal fines using various binders
(SAIMM, 2018)Inertinite-rich, low-grade coal was used with 12 binders: clays (attapulgite and bentonite), biochar, cow dung, crystallized medium-tar pitch, coal tar sludge, flocculant, fly ash, lignosulphonates, polyester resin, and ... -
Sodium silicate cold-bonded chromite pellets for the ferrochromium industry: identifying a suitable process
(Dep. de Engenharia de Materiais, 2020)Chromite fines (defined as particles smaller than 6 mm) account for a significant fraction of mined South African chromite ore. These fines are pelletized to allow safe furnace smelting conditions. However, pelletization ... -
Why is CaCO3 not used as an additive in the pelletised chromite pre-reduction process?
(Elsevier, 2013)The production of ferrochrome is an energy intensive process. At present, the pelletised chromite pre-reduction process is most likely the ferrochrome production process with the lowest specific energy consumption, i.e. ...
