Abstract
The present invention is directed generally to the combined use of slurry mining and hydrocyclones to recover hydrocarbons, such as bitumen, from hydrocarbon-containing materials, such as oil sands, and to selective mining of valuable materials, particularly hydrocarbon-containing materials, using a plurality of excavating devices and corresponding inputs for the excavated material. The excavated material captured by each input can be switched back-and-forth between two or more destinations depending on the value of the stream.
