Author:Masindi, Vhahangwele; Gitari, WM; Pindihama, KGDate:Nov 2015The use of low-cost and locally available material in the treatment of wastewater has recently become an issue of interest, and magnesite as a low-cost material has been used for the removal of heavy metals in wastewater and has also shown ...Read more
Author:Masindi, Vhahangwele; Ndiritu, JGDate:Jun 2017This study evaluated the fractional and sequential recovery of inorganic contaminants from acid mine drainage (AMD) using cryptocrystalline magnesite. Batch experimental approach was used to fulfil the goals of this study. The obtained results ...Read more
Author:Masindi, Vhahangwele; Ndiritu, JG; Maree, JPDate:Apr 2018In this study, a process of fractional and step-wise recovery of metals from Acid Mine Drainage (AMD) using calcined cryptocrystalline magnesite was explored. pH Redox Equilibrium (in C language) (PHREEQC) was used to complement the experimental ...Read more
Author:Masindi, VhahangweleDate:Aug 2017This study endeavours to report the efficiency of a hybrid approach in the treatment of acid mine drainage. Cryptocrystalline magnesite was used to pre-treat acid mine drainage and barium chloride was used to remove the residual sulphate ...Read more
Author:Masindi, Vhahangwele; Gitari, MW; Tutu, H; De Beer, MorrisDate:Oct 2015Acid mine drainage is generated when mining activities expose sulphidic rock to water and oxygen leading to generation of sulphuric acid effluents rich in Fe, Al, SO (Sup4) and Mn with minor concentrations of Zn, Cu, Mg, Ca, Pb depending on ...Read more
Author:Masindi, VhahangweleDate:Dec 2015Wastewaters originating from mining activities are usually acidic and often contain high concentrations of Fe, Mn, Al and SO 2 in addition to traces of Pb, Co, Ni, Cu, Zn, Mg, Ca and Na. This wastewater impacts surface and subsurface water ...Read more
Author:Masindi, Vhahangwele; Mugera Gitari, WDate:Feb 2016Availability of arsenic in waterbodies has posed devastating impacts to terrestrial and aquatic organisms. As such, prudent and pragmatic technologies need to be developed to troubleshoot and solve the problem of arsenic in aquatic ecosystems. ...Read more
Author:Masindi, Vhahangwele; Gitari, MWDate:May 2016The present study aimed to evaluate the efficiency of using cryptocrystalline magnesite to remove boron ions from aqueous systems. Batch experimental protocols were used to evaluate the adsorption capacity of magnesite for boron. Parameters ...Read more
Author:Masindi, Vhahangwele; Gitari, WM; Pindihama, KGDate:Jul 2015In the present study, nanocomposite of cryptocrystalline magnesite-bentonite clay was used as a novel technology for removal of phosphates from municipal effluents. Vibratory ball miller was used for fabrication of the composite. Removal of ...Read more
