A gravity mineral recovery apparatus and process (10) uses stratification to separate the relatively heavier valuable particulates from the lighter tailings in ore (O). A housing (12) holds a process chamber (14) therein, the chamber (14) capable of oscillating within the housing (12). Ore (O) is gravity fed into the process chamber (14) and falls toward the bottom with the ore (O) channeled to the outer sidewall of the process chamber (14) by a deflector (46) that creates an annular passage within the chamber (14). The oscillation of the chamber (14) causes the heavier particulate to stratify into circumferentially disposed hoppers (62) while the tailings are discharged through a central chute (58) to a tailings hopper (96). The hoppers (62) have compound sloped sidewalls (64) and have a sensor (84) for opening a discharge valve (74) within the hopper (62) once a given concentration is achieved. A series of sensors (106, 108, 1 10, 1 12, 1 14) within the tailings hopper (96) control a tailings discharge valve (102) as well as an ore feed valve (94). Water (W) constantly flows through the system (10) yet does not participate in the actual transport of the particulates. |
