dc.description.abstractENGLISH ABSTRACT: The oxidation of pyrite by the acidophilic chemolithotrophic bacterial species, Thiobacillus ferrooxidans, leads to the formation of large volumes of acid drainage, a major environmental pollution problem associated with the mining and storage of sulphide-containing ores. Measures to control acid mine drainage include the treatment of acidic effluent or the chemical or physical inhibition of T. ferroxidans. The present research was a study of the possibility of inhibiting T. ferrooxidans in gold mine sand and coal discard dumps by various chemicals, including sodium lauryl sulphate (SLS) applied to pilot scale coal discard dumps.en_ZA
dc.description.abstractAFRIKAANSE OPSOMMING: Die oksidasie van piriet deur die asidofiele chemolitotrofe bakteriespesie Thiobacillus ferrooxidans, lei tot die vorming van suur afloop. Omgewingsbesoedeling deur groot hoeveelhede suur afloop gaan gewoonlik gepaard met die ontginning en opberging van sulfiedbevattende ertse. Beheermaatreels behels die behandeling van die suur water of die chemiese of fisiese inhibering van T. ferrooxidans. Die huidige navorsing behels 'n studie van die moontlike inhibisie van T. ferrooxidans in goudmynsandhope en steenkoolafvalhope deur verskillende chemiese middels, insluitend die toediening van natriumlourielsulfaat (NLS) op loodsskaal steenkoolafvalhope.af_ZA
