Of the three stages of smelting, reductive smelting to producing black copper has the most challenging process chemistry. Other secondary copper smelting furnace technologies, such as the Blast Furnace and Top Blown Rotary Converters (TBRC), are unable to fume appreciable quantities of zinc due to kinetic limitations.
Non-ferrous metals with widely applications in machinery manufacturing [1], energy and chemical industries [2], [3], construction engineering [4], and other industrial sectors [5] were vital to the national economy. Copper as an essential nonferrous metal was always obtained by molten bath smelting from mineral powder [6].For the oxygen-rich top-blown immersion …
Bottom-blowing copper smelting technology was initiated and developed in China in the 1990s. Injection of oxygen-enriched high-pressure gas strongly stirs the molten bath consisting of matte and slag. Rapid reaction at relatively lower temperatures and good adaptability of the feed materials are the main advantages of this technology. Development and …

Most copper (80%) is extracted and refined from copper sulphides using the floatation – smelting – refining process. With the sulphides of Chalcopyrite, Bornite and Chalcocite being the most common and therefore most used in copper production. The processes of extraction, reduction and refining are complex and vary by the type of
1991 TMS proceedings volume Injection in Process Metallurgy (pages 199-213), edited by T. Lehner, P.J. Koros, and V. Ramachandran. The Mitsubishi process is a continuous copper smelting and converting process comprising three steps-smelting of raw materials by injection, separation of slag and matte, and direct converting of high-grade
Oxide Ore: The copper-bearing solution is collected and pumped to the extraction plant where it is purified. It progresses through a number of steps that combine an organic solvent or sulfuric …
The process is most commonly used for leaching low-grade deposits in situ or as heaps. Recovery of copper metal and alloys from copper-bearing scrap metal and smelting residues requires preparation of the scrap (e.g., removal of insulation) prior to feeding into the primary process.
Through reaction (4), FeO forms a liquid solution with SiO 2 in the slag phase, while it is oxidized via reaction 5 to form magnetite which remains mostly in the slag phase. The slag phase is made up primarily of FeO, Fe 3 O 4, and SiO 2 with trace quantities of copper and is considered as waste in the copper smelting process. The matte phase (copper percent by …
The authors do not include a smelting of ores into this classification. This may be explained by the fact that the insides of many earliest crucibles are covered, if at all, only by very thin, mm-thick slag incrustations (Craddock et al. 2007b).Melting experiments have shown that, e.g. copper in metallic form can be produced from small-sized ores when they are loosely …
A 1/5 scaled physical slice model of a bottom blown oxygen copper smelting furnace was established to investigate the flow field characteristics in the pool and in the freeboard above the pool.
Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and …
The predominant copper process is reverberatory furnace smelting of sulfide concentrates to produce matte and slag, followed by treatment of the matte in converters to form blister copper.
Copper production techniques have undergone a lot of development and new equipment and processes are still emerging, such as modern continuous copper smelting and converting processes (Habashi ...
Copper Smelting: Smelting is a metallurgy technique to extract base metals from their ores with the help of heat and a chemical reducing agent. (Click here for extraction process). Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in ...
Conventional copper production in a two-stage smelting process is the most popular production technology. For many types of concentrates, the combination of flash smelting with integrated heat recovery and electrolytic refining is probably the most cost-efficient route for production of high volumes of copper.
Today, chalcopyrite (CuFeS 2) is the most frequent source of copper ore, accounting for around fifty percent of copper production. Mining is the initial phase in the extraction process. Copper ore must be extracted using …

Occasionally adopted in preference to smelting (or pyrometallurgy, as it is generally known), leaching, or hydrometallurgy, is carried out at lower temperatures and …
Copper it is not the most energy-intensive metal to produce (Norgate et al., 2007) but the growing global demand (Kuipers et al., 2018) and declining ore grades (Northey et al., 2014) are likely to result in increasing environmental footprint.Ekman Nilsson et al. (2017) reviewed literature for carbon footprint of copper production. Their data did not show any …
