How Does A Submeged Arc Furnace Used To Smelter Gold. Dc submerged arc furnace saf the dc furnace is ideally suited for efficient reduction of both high and lowgrade fine ores using readily available reductants like fine coal and anthracite since fine raw materials can be fed directly into a dc furnace no additional agglomeration facility is needed
The Second World War saw a steep increase in the use of these furnaces leading to the modern Electric Arc Furnace design operation and working principles. These improvements to the processing of scrap steel comprised of larger more efficient and higher capacity furnaces; a 100T furnace would process the scrap in about an hour, using a transformer of 60MVA capacity.
Metix is not only responsible for all submerged-arc furnace and electric smelter projects in the southern African region, but also supplies feed material pre-heating systems as well as pellet and sinter plants.

Induction furnaces, which are much smaller in size than traditional resistance or arc furnaces, are becoming more popular in the gold-smelting industry due to their efficiency in batch melting.
To cheaply smelt your own gold you need to have access to a high temperature furnace. For a do-it-yourselfer this shouldn't pose a huge challenge. The first thing to do is determine the amount of gold to smelt. This will inform the size of the furnace. Small tin coffee cans or large trash cans make for good starting points in this regard.
Jul 15, 2014· Electric arc furnaces have been used for many years both for the melting of scrap iron (open arc furnaces) and for reduction processes (submerged arc furnaces). In case of the submerged arc furnace (SAF), ore and reducing agent are fed to the furnace continuously from the top so that the electrodes are buried in the mix and the arc is submerged.
