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.

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.

A method is provided for removing ultrafine particles from an atomized powder.

Systems and methods can sort materials of different specific gravities in a mixture. These systems and methods for separation of materials provide multiple forces simultaneously. The system can utilize both vertical and the horizontal forces for efficient separation of materials with different specific gravities.

The present invention is a novel gold pan and associated method for improved yield of gold during the panning process. The gold pan has a continuous curved sidewall and a base, wherein the curved sidewall and the base are used for collecting gold. A portion of the curved sidewall has a plurality of ripples, each ripple having a ridge, an extending lip, and a cavity, the cavity is used for trapping black sand and gold particles, wherein a vortex of mixture of water, gravel, sand and more is produced in the pan and upon circulating and repeating of the pan, the gravels and blonde sand is rinsed out while leaving the black sand including the gold behind. The process does not require a user to keep looking in the pan during the panning process and improves the yield of the gold or other gemstones being panned.
