When iron Fe and copper sulphate CuSO4 solution react, they undergo a single displacement reaction, also known as a substitution reaction, to form solid copper Cu and aqueous iron sulphate FeSO4 . The iron can be solid or aqueous but the copper sulphate must be aqueous in order to facilitate the reaction.
Roasted copper ore containing the copper as CuSO 4 is to be extracted in a counter-current stage extractor. Each hour a charge consisting of 10 tons of inert solids, 1.2 tons of copper sulfate, and 0.5 ton of water is to be treated. The strong solution produced is to consist of 90 percent H 2 O and 10 percent CuSO 4 by weight.
Extracting copper from other ores. Copper can be extracted from non-sulphide 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.
The copper layer could then be easily separated. Therefore, at that time, copper became the source of great wealth for Sweden. In China, another way of extracting copper was hydrometallurgy, which was one of the most important discoveries in the history of chemistry. Its chemical formula is: CuSO4 Fe=FeSO4 Cu.
The principal ore of copper is copper pyrite and copper is extracted from this ore. The different steps in extraction of copper are: Crushing and Concentration: The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized. The ore being sulphide ore is concentrated by froth floatation process.
The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of Ore: The ore is crushed into a fine powder and a suspension is created in water. To this are added, Collectors and Froth Stabilizers.
Copper Mining Lab Class Copy. Background Reading. Experiment Overview: The purpose of this experiment is to simulate heap leach extraction of copper from copper ore. Copper metal will be recovered using a single replacement reaction. Introduction: Mining is the extraction of metals or minerals from the Earth.
The typical method of recovering / extraction the copper from the malachite ore is: 1 First, crush the ore 2 Pile the crushed ore in to a heap on a liner 3 Sprinkle the pile with sulfuric acid the base reaction is: Cu OH 2 H2 SO4 = 2H2O CuSO4 4 Drain the recovered liquid into a container 5 Add some old iron pieces the reaction is Fe ...
