Method and system for extracting and refining gold from .

In FIG. 10, a process 194 for refining gold from dore is illustrated. In a first step 196, the dore is dissolved in an etchant which serves an electrolyte for an electro-extraction cell. A step 198 then causes the gold from solution to plate the electrode of the cell, and a step 200 washes and filters the precipitant from the plated cathode of the cell to produce pure gold.
