contact usThe gold solution is then ready for electrowinning, a process that extracts the gold from the leaching chemicals. The solution is poured into a cell, where it receives a strong electrical current. The gold gathers on the cell''s negative terminals. The negative terminals are melted at around 2,100 degrees Fahrenheit in a process known as smelting.
contact usAn electrowinning cell is effectively a direct-current resistance unit. One of the current carriers is the gold–deposition reaction. At the beginning of the plating cycle when the gold solution tenors are high, maximum current is needed to plate the gold.
