A device for sorting contaminants from minerals includes a mineral feeding arrangement configured to feed minerals to an elongated chute member configured thereto in an inclined position for enabling free falling of the minerals in a detection zone. The device further includes an X-ray generating member to generate at least two collimated X-rays, low and high collimated x-rays, such that the collimated X- rays passes from the free falling minerals in the detection zone for being partially absorbed thereby.; The device further includes a multi-energy X-rays sensors array to sense residual low and high energy X-rays and send a signal data to an electronic module to generate a comparative valve for determining the contaminants from the free falling minerals to be sorted based on a stored threshold valve, and send a process signal to a manifold arrangement having a plurality of ejectors to generate pneumatic-pressure for sorting contaminants from minerals.
