Abstract: Embodiments of the present disclosure provide a pressurized two-product dense-medium separation process for oil shale, and belongs to the field of oil shale industry, in particular to the processing and utilization of oil shale. This process includes: pre-screening a raw oil shale ore through a 25 mm screen; crushing an oversize product, mixing with an undersize product, and separating by a pressurized two-product dense-medium cyclone; and subjecting an underflow and an overflow of the pressurized two-product dense-medium cyclone to dewatering and medium draining respectively to obtain a concentrate and a tailing. The present disclosure has a simple process flow, high separation efficiency and low energy consumption and can reduce the cost of oil refining and achieve better economic benefits.
