| A process line for excavating and processing oil sands ore near a mine face. A mobile excavator excavates ore along the length of a mobile mining conveyor. A mobile comminutor receives and comminutes the excavated ore and transfers the comminuted ore to the mobile mining conveyor. The mobile mining conveyor conveys the comminuted ore to a transfer conveyor that conveys the comminuted ore to a mobile slurry facility. The mobile slurry facility combines the comminuted ore with process water to produce a slurry and pumps and conditions the slurry through a hydro-transport pipeline to a mobile extraction facility as a slurry feed. The mobile extraction facility receives the slurry feed and directs the slurry feed and a water stream as inputs to a three stage countercurrent cyclone separator. The cyclone separator produces a bitumen rich stream and a tailings stream. The bitumen rich stream is directed to a froth concentration unit that separates the bitumen rich stream into a bitumen product stream, a recycled water stream and a fine tailings stream. The fine tailings stream is combined with the tailings stream to produce a tailings product stream that is directed to a tailings treatment facility. The tailings treatment facility receives the tailings product and combines the tailings product with an additive to produce a treated tailings stream that is directed to a tailings pond for separation into a dry tails phase and a water phase that may be collected and recycled as industrial process water. | ||||||

| A slurry of contaminated sand and water is delivered to a solid/liquid hydrocyclone (2) surmounting a pressure vessel (1). That is divided into two sections (3, 4) by a bulkhead (5) leaving a gap between the sections at the top. The partially cleaned sand from the hydrocyclone (2) is dropped into one section (3) while the water is directed to the section (4). The sand is then fluidized with clean, preferably recycled water and directed back through the hydrocyclone (2). This is repeated several times, progressively cleaning the sand. Oil removed by the process floats on the water in the section (4) and is discharged to drain (22). Provision for degassing the pressure vessel (1), discharging the fully cleaned sand, and for flushing and draining the pressure vessel is made. | ||||||
| 113 | Cycloseparator for removal of coarse solids from conditioned oil sand slurries | US150083 | 1998-09-09 | US6119870A | 2000-09-19 | Waldemar Maciejewski; George Cymerman |
| A large capacity cyclonic separator is used for desanding a conditioned aqueous oil sand slurry comprising aerated bitumen, water and sand to produce pumpable, pipelineable lean froth and sand tailings. The cyclone separator is a vessel which forms an elongated cylindrical separation chamber and has a tangential slurry inlet at one end and, at the opposite end, a peripheral sand removal outlet and a centrally positioned vortex finder. Oil sand slurry is continually tangentially introduced into the cyclone separator to form a rotating vortex, which generates a centrifugal force. The lean froth migrates to the center of the vortex to form an inner core and is removed via the vortex finder. The sand tailings migrate to the outer reaches of the vortex and are co-currently is removed via the sand removal outlet. | ||||||

The surrounding contaminated earth to be remediated is first excavated. Then, any clay or shale which is present is separated from the other materials and transported to a site of a cement plant. The non-clay or non-shale material is disposed of in a non-hazardous landfill. At the cement plant, the clay or shale is mixed with other cement precursor raw materials and the mixture is ground to form a cement feed mix. The feed mix is introduced into a rotary cement kiln causing any remaining petroleum product contained therein to be volatilized and burned within the kiln as the cement clinker is formed. The clinker is then ground for the purpose of forming cement free of petroleum product. | ||||||
| 118 | Oil, water and sand separator | US816486 | 1992-01-03 | US5344255A | 1994-09-06 | Irfan A. Toor |
| Oil, water and sand are separated from soil by screening and separation of coarse particles, agitating the soil in a solution of non-ionic biodegradable detergent to promote emulsification of the oil, separating sand from the emulsion, separating the oil in the emulsion from the detergent solution in a coalescing filter, and recycling the detergent solution. Preferably the soil and detergent solution is agitated first at low speed to separate any aggregate from the soil, and to provide a homogenized mixture of the soil and the detergent solution, and then agitating the homogenized mixture of the soil and the detergent at high speed to transfer the oil from the soil into an emulsion with the detergent solution. For reduced maintenance of the coalescing filter, the emulsion is passed through a hydrocyclone for removing fines before the emulsion is passed to the coalescing filter. In a preferred arrangement having one additional washing stage, the sand removed from the settling tank is fed along with fines from the hydrocyclone to the additional washing stage, where the sand is washed with secondary stage wash liquid. The sand is removed from the wash liquid, and the wash liquid is fed to a flocculation tank, where contaminated fines settle and are removed from the wash liquid. The secondary stage wash liquid is recycled from the flocculation tank. | ||||||
