Copper Recovery in Smelting Slag Recycling Copper smelting slag is the solid waste generated in the process of smelting copper. Due to the limitations of the smelting technology, most of the copper smelting slag contains a certain amount of copper.
The process includes three operations similar to copper and nickel slag production: (1) roasting, (2) smelting, and (3) converting. Lead and zinc are often related as coproducts in both source and metallurgical treatments, and the various combinations of slags, which include lead, lead-zinc, and zinc, are similarly produced.

Mitsubishi Materials announced on Tuesday the firm expands berth for ore carrier at Naoshima copper smelter in Kagawa. Through the 3 billion yen investment, the smelter can accept ore carrier with 60,000 tonnes of load capacity compared with current 20,000 tonnes.
Smelting is a process of applying heat to ore in order to extract out 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.
