Effective extraction of copper from sulphide ores requires careful operation of a copper smelter, which in turn depends very much on chemistry of the feed and resulted slag and matte. For example, chemical composition of copper smelting slags has to be in a certain range to ensure that their properties are within specific limits.

In the smelting process, either hot calcine from the roaster or raw unroasted concentrate is melted with siliceous flux in a smelting furnace to produce copper matte. The required heat comes from partial oxidation of the sulfide charge and from burning external fuel. Most of the iron and 10/86 (Reformatted 1/95) Metallurgical Industry 12.3-1

The second step, involving either smelting or leaching, removes a large proportion of impurity elements—in particular iron and, in the case of sulfide ores, sulfur. The final step, refining, removes the last traces of …

The general process flowsheet of the copper smelter used for piloting the COCOP solution is pre-sented in the figure 1. The main raw materials are sulfidic copper concentrates that are first blended to feed mixture and then dried before processing. Flash Smelting Furnace (FSF) and Peirce-Smith Converters (PSC) are in the heart of the operation.

Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore …

Copper ore processing is a complex and intricate industrial process that involves extracting valuable copper minerals from raw ores. Here is an overview of the …

Aluminum processing - Smelting, Refining, Alloying: Although there are several methods of producing aluminum, only one is used commercially. The Deville process, which involves direct reaction of metallic sodium with aluminum chloride, was the basis of aluminum production in the late 19th century, but it has been abandoned in favour of the more …

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

This term is the amount of heat required to heat the input streams in the smelting stage (ore, waste sulphide and air) from ambient temperature (20ºC) to the smelting temperature (1250ºC). 2.

The effectivity of present copper smelting technologies have their roots in industrial and laboratory-scale experience accumulated over the past decades. Since early '60s, the tools for improving the processing conditions and smelting vessel design included scale modelling and manual computing of homogeneous multicomponent …

Ore processing recovery systems are used for everything from recovering precious metals, industrial minerals to processing rare earth minerals. Plants for recovering precious metals often recover ...

In the furnace, the concentrates are instantly oxidized, after which they melt and separate by their own reaction heat into copper matte with a grade of 65% and slag consisting of iron oxide, silica, and other compounds. Reaction in the flash smelting furnace. CuFeS 2 + SiO 2 + O 2 → Cu 2 S・FeS + 2FeO・SiO 2 + SO 2 + Reaction heat.
