Multiple wires run parallel to one another. Each of wires is spaced apart from each adjacent wire at a distance less than a width of an encased microchip. Each of the plurality of wires includes a plurality of straight segments in a plane and bent segments that connect two of the plurality of straight segments. For each of the wires, each bent segments includes a first end, a second end, and a curved portion curved away from the plane. The first end is connected to at least one of the straight segments and separated from the second end a distance greater than the width of the encased microchip. The curved portion includes a diameter greater than the width of the encased microchip.

A screen panel assembly includes a screen panel and a raised screen component disposed thereon. The raised screen component includes an inclined screen surface that defines a first plane oriented at a first angle relative to the screen panel and a wedge surface positioned at a back side of the raised screen component. The inclined screen surface has a front edge that is aligned with a top surface of the screen panel and is substantially perpendicular to a longitudinal axis of the screen panel, the first plane being substantially perpendicular to a displacement vector along which the screen panel assembly is accelerated by a vibratory separation device. The wedge surface is adapted to disrupt a flow path of a flow of a material mixture flowing in a longitudinal direction across the screen panel by redirecting the flow around opposing sides of the raised screen component.

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.
