A process for extracting metals having lead affinity from mineral ores. The process is in steps including, pulverizing the ore material, drying the ore, melting elemental lead in a melting chamber and maintaining the molten lead within a preselected temperature range, introducing the ore into the lower portion of the melting chamber, agitating the molten mixture, transferring the molten mixture to a cooling vessel, removing the slag and refining the remaining metallic mixture to separate the metallic components. Also, a device for extracting metals from ores including a melting chamber, heating means, an ore tube and an auger for inserting ore into the melting chamber and an agitation rod. The process and device are utilized for either small scale assaying of ore samples or commercial extraction of metals from mineral ores.
