Patent ID: 10532380

Abstract:
A method of making a circular ore separation wheel, for concentration critical stategic rare earths, and preciouse metals, such as gold. The method comprising: 1) forming a base section of the circular ore separation wheel using 3D printing; 2) forming a central hole in the base section being centrally located in the circular ore separation wheel; 3) forming a plurality of teeth, using 3D printing, upon the base section, having a inner end proximate to the central hole and extending therefrom in a circularly radiating direction and having an outer end opposite the inner end with different sizes on the same length of tooth, 4) forming a plurality of micro grooves from about 4.5-0.001 mm partially along outer surfaces of the plurality of teeth extending in a direction from the inner end to the outer end of the plurality of teeth, wherein the plurality of micro grooves are formed by the 3D printing process leaving a small gap located between subsequent extruded layers at the outer surface of the plurality of teeth; and 5) forming a circumferential wall around the ore separation wheel that is proximate to the outer end of the plurality of teeth, and is proximate to the base section. And potentially manufacturing the circular ore separation wheel inside of a pre-made support section with the desired internal concave contours.
