Re-purposing of Acid Generating Fine Coal Waste: An Assessment and Analysis of Opportunities

is paper focuses on opportunities for the re-purposing of separated sul de-rich coal tailings. e approach used in this study was based on the innovation value chain and included identi cation and preliminary analysis of alternatives, multi-criteria performance assessment of selected alternatives, and a scenario analysis of the two preferred options to achieve a better understanding of the implications of these applications in the South African context. is analysis indicated that whilst cemented paste back ll and soil amelioration were the preferred options, further developmental work would be required to establish e cacy, particularly in the case of the less promising cemented paste back ll option.
