The smelting furnaces, in this case electric arc furnaces, extract elements at high temperatures. At the same time, chemical reactions occur, such as reduction of oxides to metals. Molten metal and slag are separated inside the furnace due to their density differences. The electrical energy to the furnace is provided via carbon-based electrode(s).

Gold Melting Furnaces: A few years ago, the spotlight was after creating a microwave kiln for smelting metals and performing fire assays. The first product was a microwave kiln that was quickly followed with the creation of the 4″ which is called the Kiln. The 4″ kit comes complete, minus propane and something to smelt, of course. The Kiln has seen fantastic …

dried and heated charge for the smelting furnace. Smelting of roasted (calcine feed) or unroasted (green feed) ore concentrate produces matte, a molten mixture of copper sulfide (Cu2S), iron sulfide (FeS), and some heavy metals. Converting the matte yields a high-grade "blister" copper, with 98.5 to 99.5 percent copper.
Outotec Flash Smelting and Kennecott- Outotec Flash Converting for copper Outotec Flash Smelting combined with Kennecott- Outotec Flash Converting is an integrated solution for high-capacity smelters. Matte from the flash smelting furnace is granulated and fed to a flash converting furnace in the same fashion as concentrate.

The Electric Smelting Furnace: a key to unlock flexible direct reduction of iron ore? In contrast to an EAF, the ESF is purpose-built to process DRI and can be tailored to operate with different grades and physical shapes of DRI (e.g., pellets, fines, lump or …
The Outotec DRI Smelting Furnace is developed to tolerate high slag volumes and it is designed to work under reducing atmosphere to avoid excess iron losses and …
Smelting Furnace: The next step is to put the prepared iron ore into a super-hot furnace. It can be a blast furnace, electric arc furnace, or reverberatory furnace. These furnaces get as hot as 1,200 to 1,600 degrees Celsius (2,192 to 2,912 degrees Fahrenheit). This intense heat is crucial for reducing the iron ore into its elemental form.
