Electric Smelting Furnace of Ore With cheap electric power the furnace to be described might be used on ores, but a well-known firm with an interest in it questions that it has advantage over the standard types in smelting. On December 22, 1931, United States Patent 1,837,696 was issued to Sydney T. Wiles (not Wile) for the electrothermic reduction of iron ores.
Copper Smelting Furnace The early development of the reverberatory furnace for smelting copper ores was the work of the Welsh smelters, particularly those of Swansea. The first record of a reverberatory furnace is made by Jars, who states that copper-smelting was effected in reverberatory furnaces at Middleton-Tyas, in Yorkshire, England.

Blast furnace - Wikipedia A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with
How tin is made - material, used, processing, steps The process of extracting tin from tin ore varies according to the source of the ore deposit and the amount of impurities found in the ore. The tin deposits in Bolivia and England are located deep underground and require the use of tunnels to reach the ore. The ore in these deposits may contain about 0.8-1.0% tin by weight. Tin deposits in
