ABSTRACT The invention relates to a process to separate a mixture of water, solids or sludge, non-volatile hydrocarbons and other accompanying substances by means of solvent extraction. Mixtures which consist primarily of solids or sludge with non- volatile hydrocarbons are especially suited for application of the process in accordance with the invention if they occur as tar sands which can be mined from open-pit or underground mines. However, it is also possible to use the process to decontaminate soil contaminated by crude oil spillage. The process in accordance with the invention makes it possible to produce bitumen from tar sands without the need for storing production waste in settling ponds. This environmentally friendly process makes it possible to combine high yields in bitumen production with low energy and operating costs. Even when the bitumen content of the tar sands is low (<6%), the extraction efficiency is about 90%. The solid material left behind is ecologically harmless and the solvent used can be constantly returned to the circular process. The recycled water is free of hydrocarbons and contains a small amount of fine particles.
