Ore separator

An ore separator comprising:

• a housing;
• a charging means securely mounted on said housing;
• a means for transferring and arranging the feed in a layer one grain thick, said transferring and arranging means being made as a bowl rotatably mounted within said housing under said charging means;
• a drive for rotation of sad bowl mechanically associated with said bowl;
• a vertical annular partition arranged around said bowl and dividing the interior of the housing into coaxially disposed compartments for separation products;
• a horizontal light-insulating partition arranged in said housing above said bowl;
• at least two X-ray tubes mounted on said horizontal light-insulating partition over the area of feeding the ore to expose the ore to radiation;
• photo-electric means disposed on said horizontal light-insulated partion in a region where X-ray luminescence can be received from feed grains which have received X-ray radiation;
• air ejector means arranged on said horizontal light-insulating partition over and along the path of travel of the feed grains opposite said vertical partition, said ejector means being electrically connected to said photoelectric means and acting upon the luminescent feed grains;
• said horizontal light-insulating partition being formed with respective slots for the passage of X-ray radiation from said X-ray tubes onto the feed grains, for the passage of X-ray luminescence from the feed grains onto said photo-electric means, and for the passage of air pulses from said ejector means onto the luminescent feed grains, and said horizontal partition being provided with an opening for receiving said charging means.
