Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a metal. Both processes use electroplating on a large scale and are important techniques for the economical and straightforward purification of …
Smelting Furnace of Iron Ore Laboratory-scale experiments showed that pig irons and steels of acceptable grade can be made by arc-furnace methods from east Texas siliceous ores containing less than 25 percent iron. Under highly reducing conditions, 97 to 99 percent of the iron in the ore was recovered as pig iron. Small quantities of limestone, the minimum limited only by …
