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 pan; 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.
Claims20
A method of panning, comprising the steps of:
- a. providing a pan having a rib extending upwardly and forwardly from a reservoir of the pan;
- b. disposing particulate material within the reservoir;
- c. shaking the pan alternatingly back and forth along the rib thereby liquifying the particulate material;
- and
- d. tilting the pan forward, thereby flowing liquified particulate material over the rib.
A method of panning, comprising the steps of:
- a. providing a pan having a rib extending upwardly and forwardly from a reservoir of the pan;
- b. disposing particulate material within the reservoir;
- c. shaking the pan alternatingly back and forth along the rib thereby liquifying the particulate material;
- and
- d. tilting the pan forward to an angle wherein liquified particulate material flows over the rib, thereby releasing less dense materials from the pan while trapping heavies behind the rib.
A method of panning, comprising the steps of:
- a. providing a pan having a plurality of ribs in an array extending upwardly and forwardly from a reservoir of the pan;
- b. disposing particulate material within the reservoir;
- c. shaking the pan alternatingly back and forth along the plurality of ribs thereby liquifying the particulate material;
- d. tilting the pan forward to an angle wherein liquified particulate material flows over the rib, thereby releasing less dense materials from the pan while trapping heavies behind the rib;
- and
- e. holding the pan substantially in a tilted position with a consistent angle while additional particulate material is disposed within the reservoir behind the gate panel.
