TENORM: Copper Mining and Production Wastes

Smelting. Copper smelting involves three steps: Roasting: Ore concentrates are roasted or heated to remove sulphur and moisture. Smelting: Copper concentrates are mixed with silica (sand) and limestone then heated in a furnace to form two immiscible (naturally separating) layers.

Smelting

Smelting. 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 Production: How Is Copper Made?

Jan 14, 2019Virtually 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.

1Conversion of a crushing plant to a gold mill in a copper

In 1985, a crushing plant, located in the feed preparation area of Kidd Creek's copper smelter, was modified. The plant, which originally had treated only copper-bearing materials for the smelter, at a rate of 10 tonnes per hour, was expanded to 40 tonnes per hour capacity and modified to treat silica ores to meet the smelter's flux requirement and also gold ores from the company's Hoyle Pond

Copper Smelting Chemistry Tutorial

Copper can be extracted from sulfide ores (usually higher grade ores) by direct smelting. 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.
