Copper smelting and to a lesser degree copper mining produced ultrafine particle dust that was carried into the atmosphere on air currents created by the intense heat from smelting operations. Most of the pollution would have fallen near the smelting sites, causing health problems and .
The roasting process of the sulfide ore takes place after its concentration and melting to form matte copper, which is either Cu 2 S (chalcocite) or CuS (covellite). The roasting is exothermic as is the roasting of silver and lead sulfides.
