F. No smelting process for any copper ore calls for a higher temperature, and for most a considerably lower temperature will suffice. In the formation of the copper-bearing min-erals of Peru (Raimondi 1878: 82-3), as indeed elsewhere in the world (IForbes 1954: 585; Thompson 1958: 3), the shallower deposits or secondary ores tend to weather and ...
· Secondary Copper Smelting Area Sources: National Emissions Standards for Hazardous Air Pollutants (NESHAP) ... The rule requires the owner or operator of a new secondary copper smelter to operate a capture and control system for particulate matter (PM) emissions from any process operation that melts copper scrap, alloys, or other metals or that ...

Smelting is a process of applying heat to ore, 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.
