Nonaqueous solvent extraction is a promising technology for bitumen recovery from oil sands. In this study, influences of temperature, contact time, stirring rate, and solventtooil sands ratio (V/M) on bitumen recovery, using a mixture solvent of nheptane and toluene (V/V, 3:1), were investigated by L9 (34) orthogonal design. Under the orthogonal experiment conditions, the overall impacts ...

Green Sand: The green sand is tempered sand and contains enough amount of moisture. Greensand contains a mixture of 15% to 20% of clay, 6% to 8% of water and silica. Strength depends on the mixture of water and clay. The mixture acts as the bonding material in the sand. Greensand mold is that mold which is basically made from Green Sand.
