Abstract

This thesis investigated how the geochemistry and treatment of new capping materials produced from locally available by products may improve management of bauxite residue storage facilities. Leaching and weathering of residues coupled with byproduct blends of fly ash, organic material and gypsum decreased alkalinity, salinity, sodicity and trace element mobility of the residues. Germination and plant growth experiments showed plant growth was improved on blended byproducts compared to unamended residues. Overall, the findings suggest that blended byproduct caps utilising local materials can be a cost-effective step towards closure of bauxite residue/mine tailing storage facilities.
