Electric resistance melting furnace (for valuable metal reduction recycling)

FEATURES

A valuable metal reduction recycling melting furnace that carbon-reduces copper and precious metals contained in the incineration residue of waste substrates, and metal oxides contained in by-products of the stainless steel manufacturing process.

Equipment features	By submerging the electrode into the molten slag, the Joule heat generated directly in the slag enables highly efficient melting. The metal and slag can be easily separated by completely melting the material to be treated in the furnace.
Application example	Incineration residue of electronic boards (gold, silver, copper, lead, tin, etc.) Various waste catalysts (white metals, vanadium, molybdenum, etc.) Metal melting furnace dust and pickling neutralized sludge (stainless steel) Molten metal retention and separation of metal-containing slag (nonferrous smelting slag, etc.) Incineration residue after removing the resin content (combustible content) of waste circuit boards in an existing incinerator, etc. Briquette-formed plating sludge, etc.
others	Metal reduction reaction example Nickel: NiO+C → Ni+CO Chromium: Cr203+3C → 2Cr+3CO Iron: FeO+C → Fe+CO Iron: Fe203+3C → 2Fe+3CO Manganese: MnO+C → Mn+CO The above reduction reaction progresses in the furnace, and metal is recovered from the oxide raw material. Example of valuable metal recycling system in smelting reduction furnace A system that melts and reduces the incineration residue obtained by incinerating combustible materials such as resins in waste substrates in an incinerator, etc., and recovers metal.
