Dense-medium shallow-slot sorting machine and method for sorting by using dense-medium shallow-slot sorting machine

The invention provides a dense-medium shallow-slot sorting machine and a method for sorting by using the dense-medium shallow-slot sorting machine. The dense-medium shallow-slot sorting machine comprises a shallow-slot sorting machine body; an ascending flow material inlet arranged on the wall of the shallow-slot sorting machine body in a communicating manner; a horizontal flow inlet arranged on the wall of the shallow-slot sorting machine body in a communicating manner; an upward flow medium storage device connected with the ascending flow material inlet through an ascending flow medium pipeline in a communicating manner; and a horizontal flow medium storage device connected with the horizontal flow inlet through a horizontal flow medium pipeline in a communicating mode. Due to the fact that the ascending flow medium storage device and the horizontal flow medium storage device are independent of each other, the density of the horizontal flow medium and the density of the ascending flow medium can be optimize
