Copper Extraction from Sulfide Ores - Latest Contents

This process is used for the extraction of copper from low grade sulfide ore. In this process, the crushed and ground ore in bulk (about 100,000 tons) is exposed to air and water in big tanks. The air in the presence of water gradually oxidizes copper and iron sulphides to their surphides. The process is completed in about one year.Direct extraction of copper from copper sulfide minerals,,Abstract. Copper is predominantly recovered from sulfide ores by pyrometallurgy – an energy intensive process requiring capture and treatment of released SO 2. Whilst some copper ores are amenable to hydrometallurgy, chalcopyrite, the main copper mineral, is challenging to process in aqueous solutions due to surface passivation.Extraction of copper from sulphides - Free ZIMSEC,,Copper is extracted from various types of ore including sulphide ores; For example copper ores found on the Great Dyke near Mhangura is of the sulphide type; Once the sulphide ore is extracted from the earth; It is crushed to form a very fine powder which is then further refined using; The flotation process or the concentration process

In the extraction of copper from its sulphide ore, the,

In the extraction of copper from its sulphide ore, when ore is subjected to roasting, some of it is oxidised to Cu 2 O which reacts with the remaining Cu 2 S (sulphide ore) to give copper metal. Cu 2 S +2Cu 2 O → 6Cu +SO 2 ↑ In this process, Cu 2 S behaves as reducing agent.How is copper extracted from its sulphide ore? Explain the,,Then electrolytic refining of copper is carried out to remove the rest of the impurities present in the ore. The impure copper is made anode and strip of pure copper are made cathode. On passing the current as shown in the diagram, the pure copper from the anode dissolves into an electrolyte. An equivalent amount of copper is deposited on the cathode.How is Copper Extracted from Its Sulphide Ore? Explain the,,Copper is a metal that is present low in the reactivity series. It mainly occurs in nature in the form of sulphide ore which can be converted into the corresponding oxide simply by heating in the absence of air, a process known as roasting.
