Non-ferrous extractive metallurgy - Wikipedia

The metal ore is either distilled in a electrolyte or acid solution, then magnetically deposited onto a cathode plate (electrowinning); or smelted then melted using an electric arc or plasma arc furnace (electrothermic reactor). Another major difference in non-ferrous extraction is the greater emphasis on minimizing metal losses in slag.
