Advantages of steps involved in extracting copper from its ore

how are metals extracted from ores? what are the variousto obtain a metal from its ore is called extraction of metal.the three major steps involved in the extraction of metal from its ore are as under. 1 ) *concentration of ore* the removal of unwanted impurities present in an ore is call concentration...extraction of copper from copper pyrite grade sciencethe different steps in extraction of copper are crushing and concentration, roasting, smelting and bassemerisation. the principal ore of copper is copper pyrite and copper is extracted from this ore.estimated reading time 3 minsncert exemplar class 10 science chapter 3 metals and nonsep 27, · (i) given below are steps for extraction of copper from its ore. write the reaction involved. (a) roasting of copper (i) sulphide (b) reduction of copper (i) oxide with copper (i) sulphide (c) electrolytic refining (ii) draw the neat and labelled diagram for electrolytic refining of copper. answer (i) (a) 2cu 2 s(s) + 3o 2 (g) > 2cu 2the extraction of copper chemistry libretextsjun 07, · copper can be extracted from nonsulfide ores by a different process involving three separate stages reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper (ii) sulfate solution. concentration of the copperscience question world class x solution of metal andaug , · . zn is the metal that lies in the middle of the activity series, these metals are extracted from its sulfide ore. outline the steps involved in the process of extraction of zinc metal with the help of a balanced chemical equation for each staple. ans. the metal in the middle of the activity series such as zinc is moderately reactive.metallurgy of copper slidesharedec 06, · 3. extraction of copper copper is mainly extracted from its sulfide ores by smelting. following steps are involved in the extraction of copper 4. concentration finely crushed ore is concentrated by froth floatation process. crushed ore is suspended in water containing a little amount of pine oil.extraction of copper mining, concentration, smeltingthe copper extracted from this process is mixed with the slag and is called matte copper due to its texture and appearance. this mainly consists of cu2s which is reduced to pure metal by blasting matte copper with air. cu 2 s+o 2 2cu+so 2. the sulphur dioxide escapes the copper and this causes bubbles to appear and burst as so2 leaves. this causes the final product to have a very blistery appearance and hence it is called blister copper;estimated reading time 2 minsnotes occurrence and extraction of metalsimpurities present and chemical composition of the ore. some common steps involved in the extraction of metals from their ores are (i) crushing and pulverization (ii) concentration or dressing of the ore (iii) calcination or roasting of the ore (iv) reduction of metal oxidessteps involved in extraction of metals winner sciencejul 28, · there are different steps involved in extraction of metals. let us discuss them one by one 1. crushing and grinding. first of all, ores are crushed into a fine powder in big jaw crushers and ball mills. this method is called pulverization. 2. concentration (dressing) of ores. the technique of removing gangue, the rocky impurities like sio 2

The case of steps involved in extracting copper from its ore

copper extraction and purification chemguidecopper can be extracted from nonsulphide ores by a different process involving three separate stages reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(ii) sulphate solution. concentration of the copper(ii) sulphate solution by solvent extraction.copper mining and extraction sulfide orpper can be extracted from its ore by underground sinking a vertical shaft into the earth to an appropriate depth and driving horizontal tunnels into the ore. open pit 90% of ore is mined by this method. ores near the surface can be quarried after removal of the surface layers. the ore is treated with dilute sulfuric acid.eliminating copper from g oreoct , · when reviewing methods of eliminating copper from g ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidation.preliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite, azurite and chrysocolla but these acids have but little effect on sulphide copperbiological methods of metal extraction higher materialfor example, highgrade copper ores, which contain a high percentage of copper, are becoming harder to find and mine. there are some alternative methods to extract metals from lowgrade copperextraction of copperlarge amount of copper are obtained from copper pyrite (cufes2) by smelting. ores containing 4% or more copper are treated by smelting process. very poor ores are treated by hydrometallurgical process. extraction of copper by smelting process following steps are involved in the extraction of copper. crashing and grinding the ore is crushed then ground into powder. concentrationfloatation process. the finely crushed oreprocess of the extraction of copperextraction of copper from sulphide ore large amount of copper are obtained from copper pyrite (cufes2) by smelting. ores containing 4% or more copper are treated by smelting process. very poor ores are treated by hydrometallurgical process. extraction of copper by smelting process following steps are involved in the extraction of copper.
