Copper Smelting Slideshow
Slag from the smelting process can contain up to 20% copper. It's allowed to cool and then reused in the smelting furnace to control the temperature, or it's treated by grinding and flotation and fed back into the smelting process to recover additional copper. Slag. Blister copper is only 90% pure copper. This

Iron processing
Iron processing - Smelting, Refining, Alloying: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is …

How gold is extracted by Cyanidation Process
Cyanidation is a method used in the extraction of gold from its ore. This extraction is done by converting the gold to a water-soluble form. The cyanidation process of gold extraction or the use of cyanide is the most common leaching process, used in the extraction of gold from its ores. Some countries do not approve of this method of gold ...

Technology Innovations in the Smelting of Chromite Ore
The convectional smelting process is designed to handle only lumpy ores which are ideal for ferrochromium production as the fine ores tend to form a sintered layer at the top of the charge, preventing gas escape and thus causing operating difficulties (Buchanan, 2001).
