Pyrometallurgy of copper–nickel–iron sulphide ores: .

 · A basic principle of many processes for extracting copper and nickel from sulphide ores is to overlay the molten ore or matte with a lime–silica–iron oxide slag and blow with air or oxygen. Some of the iron present in the ore oxidises and, as a result, partitions to the slag phase, while some of the sulphur is carried off as sulphur dioxide.The Extraction of Copper - Chemistry LibreTextsSulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores.

This process is a dry process. In this process, the sulphide ore is concentrated by froth floatation process. In this process, the sulphide ore .Webinar | Sulfuric Acid Monitoring in MiningCopper sulphide ores are processed by flotation. SO 2 is produced during the pyrometallurgical extraction. This is oxidized to sulfur trioxide (SO 3) (contact process) and the SO 3 is introduced into 96% sulfuric acid in the absorber, whereby highly concentrated H 2 SO 4 .ENFM - Extraction of Non Ferrous Metals | | .Copper.

Most of the copper produced in the world (80% 90%)- is coming from sulphide ores that require oxidation at high temperatures requiring pyrometallurgy treatment. However, pyrometallurgical processes produce large quantities of slag, and this constitutes one of the main by-products of the metal extraction industry [2].flow chart pyrometallurgical extraction of copperCopper Mining & Extraction Process Flow Chart. 1 pyrometallurgically to fire refined copper 2 electrolytically to high purity electrolytic copper Figure 3 Typical flow sheet for pyrometallurgical copper production from ore concentrates The large blast and reverberatory furnaces of the 1900s were derived from these principl Later .A TECHNO-ECONOMIC COMPARISON OF .About 90% of world copper production is produced pyrometallurgically from sulphide-based copper minerals, with the remainder from oxide-based copper minerals (Ayres . et al, 2002, Davenport . et al, 2002). Among the copper sulphide minerals, the main one is chalcopyrite (CuFeS. 2) comprising 50% of total copper production (CDAA, 2012).
