A hydraulic density separation device for separating a heavy material fraction with components of higher density from a light material fraction with components of lower density from a feed material includes a conveying device for conveying away the heavy material fraction, receiving chamber which can be filled with water for receiving the feed, a flow generator for generating a water flow in the receiving chamber and a water-fillable separation chamber for receiving the light material fraction. The conveying device has a shaft with a screw conveyor section for conveying the heavy material fraction out of the receiving chamber. The flow generator is designed and arranged such that a flow path of the water flow leads from the receiving chamber into the separation chamber. The conveying device has, in addition to the screw conveyor section, at least one washing section having a plurality of separate paddles arranged on the shaft.

A system configured to separate minerals is disclosed. The system may include one or more crushers configured to crush ore. The system may further include a hydrocyclone configured to receive and process a feed to divide the feed into a first feed portion and a second feed portion. The feed may be a mixture of crushed ore and water. The system may further include a plurality of spiral circuits configured to process the second feed portion to divide the second feed portion into concentrate and tailings. The concentrate may include copper and the tailings may include basalt. The system may further include one or more processing components configured to process the tailings to form a supplementary cementitious material.
