3. Thus, the gold particles are in electrical contact with that electrode. Since secondary electrowinning may also be carried out simultaneously in that cell, the gold from both sources is effectively combined at the cathode. However, initially the EWEF cell was used on its own to electrowin gold from original and diluted eluate solutions.
In gold electrowinning process,when the electrolysis equipment is added with anions that are more easily absorbed by activated carbons, AuCN2 is replaced by anion and the gold desorption is achieved. After the carbons loaded with gold are desorbed, pregnant solution processes the via ionization. At last, the solid gold is attained.

Jan 01, 2016 Electrowinning is most often used to recover gold and silver from eluates produced by the elution of activated carbon. Some of the practical considerations involved in the design and operation of gold electrowinning cells are described in this chapter, including cell types, bullion removal, and special applications such as electrowinning from gravity concentrates, and sulfide oxidation filtrates.
The main advantages include that it is non-toxic, is recyclable, extracts gold faster than cyanide, does not use water, and does not require carbon or electrowinning. The company undertook Stage 1 testing on a high-grade gold ore grading an average of 48.87 gt.
In this case, gold is deposited on cylindrical steel wool cathode, The anode is stainless steel. Steel wool was used in the first electrowinning cells used in gold mining operations, it is a good unit and leaks are not a problem. It is interesting to indicate that as the gold deposition takes place, the available surface area tends to decrease.
