  • Efficiency of remobilisation of chromium precipitates in an aquifer permeable reactive barrier 
    Kaimbi, Lapaka Albertina; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2018)
    Chromium exists largely in two oxidation states, namely Cr(VI) which is carcinogenic and mutagenic to living organisms including humans, and Cr(III) which is about 1,000 times less toxic than Cr(VI). It is therefore ...
  • In situ bioremediation of chromium (VI) in a simulated ferrochrome slag 
    Bansal, Neetu; Coetzee, Johan J.; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2017)
    Stability of chromium in the tailing dumps and stockpiles of chromium concentrate at chrome mining fields is affected by pH, redox potential, and the presence of other metallic species in the waste rocks. It is desirable ...
