Extractive Metallurgy of Copper ScienceDirectCopper Mining and Extraction Sulfide Ores

It describes that most copper is extracted from sulfide minerals so that sulfur in some form is a byproduct of most copper extraction process The usual byproduct is sulfuric acid made from sulfur dioxide that is produced during smelting and converting The production of sulfuric acid entails the cleaning and drying of the furnace gases Place these products in the extraction process in ascending order of copper content Use the flow chart as a guide Matte Ore Cathode copper Blister Anode copper Copper concentrate Fire refined copper Use a periodic table to find the atomic masses of the elements in cuprite and chalcocite Then work out the percentage of copper in each mineral

How is copper extracted from malachite ore QuoraCopper mining From ore to copper SchoolSciencecouk

May 28 32 Copper is leached with sulfuric acid from crushed oxide based or The refined copper from this process is classified as SXEW Solvent Extraction ElectroWon I visited a copper mine in Arizona where this process was used Crushed ore is sp The copper is recovered by electrolytic refining Advantages of this process are much less energy is use than in traditional mining no waste gases are given off it can be used on ores with as little as 01 copper for this reason leaching extraction is growing in importance

123 Primary Copper SmeltingBenefits of Agglomeration in an SX EW Process for Copper

Copper is produced in the U S primarily by pyrometallurgical smelting methods Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrat Process steps include mining concentration roasting smelting converting and finally fire and electrolytic refining Process Description2 4The process of extracting the copper from the solvent is typically carried out in mixer settlers which use different types of extractants to purify the copper in two stag The result is high grade electrolyte bearing copper Electrowinning Electrowinning copper from the electrolyte is done through a process known as electroplating

Nickel processing BritannicaRecovery of Copper by Solution Mining Methods AZ

The extraction of nickel from ore follows much the same route as copper and indeed in a number of cases similar processes and equipment are used The major differences in equipment are the use of higher temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production2 Recovery of Copper by Solution Mining Methods Solution mining replicates the natural process of oxidation and reduction described above Dilute acidic solutions are introduced to the copper bearing ores causing dissolution of soluble copper minerals Table 1 remaining in the leached cap and underlying enrichment blanket
