secondary copper smelting process pretreatment smelting

BACKGROUND REPORT SECONDARY COPPER SMELTING,

2.2 Process Description Secondary copper recovery is divided into four separate operations: scrap pretreatment, smelting, alloying, and casting. Pretreatment includes the cleaning and consolidation of scrap in preparation for smelting. Smelting consists of heating and treating the scrap for separation and purification of specific metals. Alloying involves the addition of one or

AP-42, CH 12.9: Secondary Copper Smelting

Fugitive emissions occur from each process associated with secondary copper smelter operations. These emissions occur during the pretreating of scrap, the charging of scrap into furnaces containing molten metals, the transfer of molten copper from one operation to another, and from material handling. When charging scrap into furnaces, fugitive emissions often occur

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 Smelter Production - MTLEXS.COM

Smelting is the pyrometallurgical process used to produce copper metal. In 2012, world copper smelter production reached 16.7 million tonnes copper. Recently, the trend to recover copper directly from ores through leaching processes has been on the increase. Primary smelters use mine concentrates as their main source of feed (although some use copper scrap as well).

Characteristics of PCDD/F emissions from secondary copper ...

01.01.2015  Copper content in secondary copper smelting processes are commonly higher than 60% and even >99% for red copper. Therefore, the potential of PCDD/F formation may be enhanced with high copper content in secondary copper smelting processes. Moreover, carbon-containing residues, such as insulation of wire and lubricant in raw materials, may also

01.01.2013  In the secondary copper smelting process, there are distinctly different smelting stages. Some secondary smelters perform all purification stages using reverberatory furnaces or converters, while some plants purify the scrap in the reductive atmosphere of a blast furnace and then purify the charge in the oxidizing atmosphere of a converter ( US-EPA, 2006 ).

Copper Recycling - ScienceDirect

01.01.2014  The copper-smelting unit also processes secondary materials such as printed circuit board scraps and sludge. It was considered necessary to keep track of impurities owing to the complexity of raw materials. One way to overcome the build-up of impurities in the plant due to recycling was to install a hydrometallurgical plant to treat dust from smelting units. The

Copper Processing - University of Illinois Urbana-Champaign

Secondary copper processing involves two steps: metal pretreatment and smelting. Pretreatment includes cleaning and concentrating the copper. Concentrating is done manually or mechanically and includes sorting, stripping, shredding and magnetic separation. The metal can be further refined using pyrometallurgical methods — including sweating, insulation burning, or
