Gold pan with classifier

An apparatus for separating particulate matter of disparate specific gravities from a carrier fluid comprising;

• a lower gravitational pan and an upper filtration pan, said lower pan having an elongated elliptical shape having two inclined end walls, a first and second pan inclined side wall, and a horizontally, centrally located bottom wall, said first and second inclined walls extending upwardly and outwardly from said bottom wall to a first height, said end walls extending obliquely upwardly and outwardly from said bottom wall to a second height, each said wall having an interior and exterior surface, a plurality of transversely extending ridges projecting from the interior surface of a first portion of said first side wall and encompassing said second side wall and both ends to a second portion of said first wall, and a plurality of transversely extending steps overlapping at least a portion on said ribs of said second side wall projecting from the exterior portion of said second side wall;
• said upper pan having an elongated elliptical shape having two inclined end walls, a first and second inclined side wall, and a horizontally, centrally located bottom grid, said first and second inclined walls extending upwardly and outwardly from said bottom grid to a first height, said end walls extending obliquely upwardly and outwardly from said bottom grid to a second height, each said wall having an interior and exterior surface with a plurality of longitudinal axis perpendicular support members projecting from the exterior surface of each of said walls, wherein said upper pan is operatively associated with said lower pan by said support members of said upper pan maintaining said upper and lower pan in a predetermined position.
