Copper extraction - WikipediaUntil the latter half of the 20th century, smelting sulfide ores was almost the sole means of producing copper metal from mined ores (primary copper production). Davenport, et al, noted . Copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. The smelters were.copper mining process direct smelt,Smelting - WikipediaSmelting is a process of applying heat to ore in order to melt 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.
