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.

Abstract: Disclosed is a material separation apparatus with a circular ore separation wheel and a number of projected spiral portions, tilted towards a central hole, provided on a concave shaped interior surface. A pair of adjacent projected spiral portions forms less than 90 degree angle to create a negative draft for an upward movement of the heavy materials during rotation of the circular ore separation wheel. The central hole of the circular ore separation wheel is attached with a central hub to rotate the circular ore separation wheel to trap the collected heavy materials in between the adjacent projected spiral portions. The circular ore separation wheel is kept in a tilted position, forming a predetermined tilting angle with the vertical, is rotated at a predetermined speed to help the created negative draft to separate the heavy material(s) from a mixture of heavy and light materials fed into the circular ore separation wheel.
