How Electrolytic Refining Works
Gold. The Wohlwill process for refining gold uses hydrochloric acid as the electrolyte. In this process, a gold alloy serves as the anode, and a thin sheet of high-purity gold acts as the cathode. When an electric current is applied, gold ions from the anode dissolve into the electrolyte, migrate to the cathode, and deposit as pure gold.

Arc Furnace vs. Induction Furnace
Arc furnaces, also known as electric arc furnaces (EAF), utilize the heat generated by an electric arc to melt and refine metals. The process involves passing an electric current through an electrode, creating an arc that generates intense heat. This heat is then used to melt the metal charge, which typically consists of scrap metal.
