Heat Recovery and Energy Optimization in Smelter Gas Cleaning

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. The reducing agent is commonly a fossil

12.3 Primary Copper Smelting

A typical pyrometallurgical copper smelting process, as illustrated in Figure 12.3-1, includes 4 steps: roasting, smelting, concentrating, and fire refining. Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as a dried and heated charge for the smelting furnace.

calcining and smelting. Calcining involves prolonged heating of the cathodes at 750°C, the purpose being to oxidise the impurities (iron, copper etc) that are present with the gold so that they can be 'slagged off' in the subsequent smelt. During smelting the calcined cathodes are heated in a gas-fired furnace to a molten state in the
