Open Access Theses & Dissertations
In this research, different options in the preparation of activated carbon are investigated looking at potential environmental impacts, production cost improvement and physical characteristics for water treatment. The activated carbon made with agricultural waste is compared to activated carbon made with hard coal. Life cycle assessment techniques follow ISO 14040 to 14044 standards are used and calculations were performed using GaBi _education 18® software and databases at mid-point TRACI impact categories. The results of the life cycle impact assessment show that, compared to activated carbon made with hard coal, activated carbon made with peanut shell and rice husk allows reductions …

This study was conducted to determine the effectiveness of three different adsorbents for the adsorption of gold from a real cyanide leach liquor. An activated carbon (NORIT GAC 1240), strong base (Purogold A194), and weak base (Purogold S992) resins were tested as the adsorbents. The pregnant leach solution (PLS) was derived from cyanide leaching (1.5 g/L NaCN, 25% w/w solids ratio, 1.5 L/min air flow rate, pH 10.5 – 11, 24 h) of the roasted copper-rich refractory gold ore pretreated with H2SO4. Gold and copper concentrations in the PLS were analysed to be 26.1 mg/L Au and 62.4 mg/L Cu, …
