A system and method for the reuse of solids rich water like fine tailings or lime sludge for extracting bitumen from shallow and deep underground oil sand formations comprising the steps of mixing hot combustion gas with solid rich water under pressure. Gasifying the liquid water to gas phase steam and solids. Removing the solids from the gas phase to generate solid lean gas phase. Mixing the gas with process water to condense the steam and recover the gas heat and using the generated hot water for extraction the bitumen from oilsands. For generating steam the solid lean gas phase is mixed with saturated water to scrub the remaining solids and produce saturated steam. The solid rich saturated water recycled and gasified by mixing with the combustion gases and the saturated steam is condensed to generate heat and clean condensed water for steam generation for use for EOR.
