most metallurgical operations is to chemically reduce them to their pure metallic form. The question is how to convert highly impure metal ores into purified bulk metals. A vast array of operations have been developed to accomplish those tasks, one of which is electrowinning. In an ideal case, ore is extracted into a solution which is then subjected to electrolysis. The metal is deposited on the cathode. In a practical sense, this idealized process is complicated by some
