AP-42, CH 12.9: Secondary Copper Smelting
The principal pollutant emitted from secondary copper smelting activities is particulate matter. As is characteristic of secondary metallurgical industries, pyrometallurgical processes used to separate or refine the desired metal, such as the burning of insulation from copper wire, result in emissions of metal oxides and unburned insulation. Similarly, drying of chips and borings to …
Copper Scrap - an overview | ScienceDirect Topics
Secondary scrap smelters primarily use TSL furnaces and top-blown rotary converters for smelting low Cu-grade scrap. The main smelting product is molten black copper (80% Cu), which is converted to rough copper (96% Cu) then fire refined and cast into anodes (98.5% Cu).
Problems in Secondary Copper Smelter: Possible …
Based on the source of copper, copper smelter method is divided into two categories: primary copper smelter and secondary copper smelter. If the source of copper material came from earth (ore), then it is primary copper smelter. But, if the source came from scrap (pipe, wire, bushing, bearing, etc), then it is secondary copper smelter.

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.Smelting uses heat and a stone reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
