Smelting

Smelting is the opposite of an oxidizing reaction to roasting. Process of Smelting. We use a reverberatory furnace in the industrial smelting of copper. Also, we pour concentrated ore and a liquid, normally calcareous, into the rim, and molten matte— a mixture of copper, steel, and sulfur— and pull out the slag from the bottom.

The Mitsubishi Process, History

New Mitsubishi Process plant was established, with a design capacity of 204,000 mtpy copper. This new Mitsubishi Process plant has, as planned, successfully rationalized Naoshima's copper operations by completely replacing the older conventional (Reverb/P-S) smelter, the original Mitsubishi Process plant, and their respective anode casting plants.

Copper Smelting Chemistry Tutorial

The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC. Copper can be extracted from oxide ores using electrolysis (electrowinning) for low grade ores, or by the carbon reduction method of smelting for higher grade ores. The process of extracting copper from higher grade sulfide ores involves:

copper ores melting furnace process

Smelting . Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores including silver iron copper and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore driving off other elements as gases or slag and leaving the metal base behind.

Copper Mining, the King of the Oquirrh Mountains

He initiated new methods of extracting metal by "floating" the ground ore on water and chemicals to extract the copper and other minerals. This process, called "concentrating," separates copper minerals from waste material. Smelting extracts copper from these minerals, and refining purifies the metal.

Virtually all sulfide-type copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting.After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic.

Mar 13, 2010The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag
