Zusammenfassung:	In the customary process for mining oil sand comprising open cast excavation, the oil sand, after being excavated and transported to the processing plant by means of trucks, is comminuted in a mill and then slurried with water for transport of the hydrated material to the extraction plant. The hydration transport already leads in each case to a reduction in surface tension of the bitumen around the individual grains. In the prior art, flotation or separation tanks are used, with use of steam. According to the invention, spontaneous emulsion breaking of the oil-water-sand mixture is forced, forming three different material phases, of which the first phase essentially comprises the oil. In the corresponding apparatus, a pressure cell is present for this purpose.
