Smelting - Wikipedia
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.

Introduction to Copper Smelting Techniques. Copper ore typically contains only about 0.6% of the actual copper mineral, the most common ore mined being chalcopyrite. The ore is attained using traditional methods of underground and open pit mining, the later accounting for 90% of the ore used in smelting.

Copper Smelting Chemistry Tutorial - AUS-e-TUTE
A typical copper ore contains between 0.5% and 2.0% copper. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal. 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 Smelting Furnace
The early development of the reverberatory furnace for smelting copper ores was the work of the Welsh smelters, particularly those of Swansea. The first record of a reverberatory furnace is made by Jars, who states that copper-smelting was effected in reverberatory furnaces at Middleton-Tyas, in Yorkshire, England. The first patent, of any importance, for improvements in reverberatory furnaces ...

Smelting caused much of the ecological damage via acid rain and elevated levels of copper and nickel in the vicinity of the smelters. Efforts by government and industry since the 1970s have eliminated most of the sulfur dioxide emissions in the area, and there has been significant progress toward achieving sustainable ecosystems.
