Abstract Bitumen extraction from surface-mined oil sands ores at a gigantic scale produces enormous volumes of fluid fine tailings (FFT) as a waste that are deposited in oil sands tailings ponds (OSTP). Increasing footprint of OSTP and related environmental consequences have drawn public scrutiny and warrant effective management of FFT. OSTP harbor diverse microbial communities that drive many biogeochemical processes in OSTP. In this chapter, we describe the microbial pathways of methanogenesis, and sulfur, nitrogen, and iron transformations in tailings that mitigate toxicity of organic constituents through biodegradation, accelerate consolidation of FFT, and regulate greenhouse gas emissions from OSTP. These microbial processes can also affect FFT reclamation under end-pit-lake (wet) scenario. Understanding microbial and geochemical composition of tailings will help design better strategies for utilizing tailings products for upland (dry) reclamation as well.
