Title: PAN AND METHOD OF PANNING
Abstract:
A gold pan and method of panning, A concave pan with lip and an array of curved ribs with linear central regions coupled to and extending above and forward from lip, each rib including a cavity oriented to be orthogonal to the concavity of the pan to trap material flowing thereover. The lip has a front region with a greater radius of curvature than a radius of curvature of a back region. There are a plurality of finishing fins extending into an interior of the concave pan from a back wall or side wall thereof. Panning is performed by disposing particulate material within a provided pars; flowing material over the ribs; flowing material over a plurality of finishing fins; collecting particulate material in a corner of a flat bottom; tipping the pan; and tapping a side thereof to separate heavies.
