 Appl.No PCT/DE1998/000591 Applicant KLEIN-SCHELL, Hans-Peter Inventor KLEIN-SCHELL, Hans-Peter
The invention relates to a method for treating waste water from gold mines in order to obtain drinking water. The raw water is treated in such a way that raw materials can be recovered for technical use and the cleaned water is suitable for drinking. Most importantly, barium is used to precipitate the sulphate and the barium compounds are circulated. The method comprises the following steps: 1. precipitation of iron and manganese through the introduction of air and/or by raising the pH; 2. precipitation of the lime by adjusting the pH and or the carbonic acid balance; 3. removal of the sulphate with barium (barium sulphide/sulphate process or barium sulphate process) and re-treatment; and 4. purification (adsorption) of the residual substances.

A process for the biological treatment of bitumen froth tailings produced from a tar sands treatment and bitumen froth extraction process is disclosed. In this process bitumen froth tailings, containing native hydrocarbon metabolizing microorganisms, are mixed with a growth media to form an inoculum which is then incubated under isothermal conditions for an amount of time to produce a mixed bacterial culture containing bioliquor and a water product containing a reduced amount of asphaltenes as well as solids such as clays and sands. The bioliquor produced in this process is then utilized in the initial tar sands conditioning process from which bitumen froth is produced as well as in the initial tar sands mining process via bioliquor injection directly into the tar sands formation. Because the mixed bacterial culture is made up of a number of hydrocarbon metabolizing microorganisms, the bioliquor is also used in the degradation of the asphaltenes. The treatment results in a process for decreasing the amount of waste produced in bitumen extraction processes. Furthermore, because the invention utilizes a biosurfactant containing bioliquor in the initial tar sands conditioning process, bitumen froth can be produced at lower temperatures and without requiring the use of caustic soda, as is conventionally practiced. Thus, the present invention advantageously avoids the production of tailings sludges caused by clay dispersion.

A process for the extraction of bitumen from bitumen froth generated from tar sands is disclosed. In this process, bitumen froth (9) is extracted from tar sands using a water process without requiring the use of caustic soda. The froth is treated in a counter-current decantation circuit with a paraffinic solvent to remove precipitated asphaltenes, water, and solids from the bitumen froth. A dilute bitumen product is produced having a final water and solids contents of about 0.01 to about 1 % by weight (32). This renders the dilute bitumen product amenable to direct hydrocracking. The process advantageously avoids the production of tailings sludges caused by clay dispersions. The present invention also includes a novel process for the biotreatment of bitumen froth tailings (47-52) resulting in a reduced amount of waste products and byproducts.
