CO2 reactivity of briquettes derived from discard inertinite-rich Highveld coal using lignosulphonate and resin as binders
(SAIMM, 2019)South African collieries generate approximately 31 Mt of fine and ultrafine coal annually, with the majority of the ultrafine fraction discarded in slurry ponds and underground workings. Use can be made of this energy ... -
Effect of fine coal tailing porosity on the mobility and speciation of heavy metals in the leachates
(EARET, 2018)The effect of porosity of coal tailings on the mobilization and speciation of heavy metals is important for the implementation of management strategies. In this study, column leaching experiments were carried out to ... -
Some physical and chemical characteristics of calcium lignosulphonate-bound coal fines
(SAIMM, 2018)Low-cost calcium lignosulphonate (CL), which is a byproduct of theWOOD pulping industry, was investigated as a potential binder during laboratoryscale pelletization of inertinite-rich high-ash coal fines from the ... -
Transport properties of chitosan membranes for zinc (II) removal from aqueous systems
(Elsevier, 2017)Chitosan materials that were prepared from different sources of fishery waste were subsequently characterized and the influence of molecular weight (Mw) and degree of deacetylation (DDA) on the chitosan-acetic acid solution ... -
An understanding of the porosity of residual coal/char/ash samples from an air-blown packed bed reactor operating on inertinite-rich lump coal
(Elsevier, 2012)The thermal treatment of coal causes a development of internal porosity of the resultant char due to the changes in the coal char pores, i.e. the opening of original closed pores, the formation of new pores, and an ...
