Teck's CESL Copper Process was developed as an alternative to conventional smelting and refining of copper concentrates for the production of LME Grade A copper cathode [5]. As shown in Figure 1, the technology is based on the combination of a few well-known and established industrial processes (i.e. pressure leaching, solvent extraction and ...
Optimal scheduling of copper smelting process is an ongoing challenge due to conflicting objectives of the various process units and the inter-dependencies that exist among these units. To design a scheduling framework, two potential alternatives – centralized and hierarchical approaches – can address those inter-dependencies in this process.
Figure 6-2.—Early Smelting Technology Charcoal ore flux m The Egyptian copper smelting furnace was filled with a mixture of copper ore, charcoal and iron ore to act as a flux. It was blown for several hours by foot or hand bellows. By the end of the smelt the copper had separated from the slag, which was tapped off.
Flash Smelting and Flash Converting process. With flexibility, low energy consumption, high sulfur capture, and excellent economy of scale, Outotec Flash Smelting technology is the world's leading method for copper and nickel smelting. More than half of the world's primary copper and nickel is produced using
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. The offgases from the reverberatory furnace are usually not more than 2 percent SO2, and of varying SO2 content from the converters, precluding economic ...
The non-ferrous smelting industry is a major polluter of heavy metals, and investigations on the flow of heavy metals in the metallurgical process are important references and the basis for optimization of the smelting process and control of heavy metal pollution. In this work, using a typical copper smelter as the research object, we examined and analyzed …
In the converter, coal is added to the matte to change the chemistry and help accumulate any remaining impurities like iron (Fe) and quartz …
Optimizing complex industrial processes, such as copper smelting, accurately has proven to be challenging with traditional methods. The process includes combinations of interlinked continuous and batch unit processes and further many of the control actions require manual actions from the process operators. Changing process bottlenecks and other limitations in real life have …

Flash smelting furnace (FSF) technology by Outokumpu is one of the most widely employed methods for copper smelting. Developing an understanding of the impact of the process parameters on smelting operation through modelling is …
copper oxides have been in common use for some time. Prior to the development of the Sherritt-Gordon process for nickel and cobalt in which copper is recovered as high grade copper sulfide, copper sulfides were economically recovered in a hydrometallurgical process only during the leaching of waste dumps. . Need for Hydrometallurgical Processes
smelting process consumes, in addition to electrical energy, about 1.95 tonnes of alumina, 0.5 tonnes of anode coke, and small amounts of fluoride salts. 2 By G.W. Bulian. 11 The electrolysis cell, or "pot," shown schematically in Fig. 2.4, is shaped like a shallow rectangular basin. It consists of a steel shell with a lining of fireclay ...
A basic flowsheet of smelting and refining can be found below [1, 2]: In a first step, smelting takes place in different types of furnaces depending on the raw materials and the process technology. An upper layer of slag and a lower one of matte, which has a copper content of approximately 55% form in the furnace.
