    03/10/2013· Extracting of Copper from Other Ores. Copper can be extracted from non-sulfide 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

  • Copper mining and the copper extraction process

    How does the copper extraction process work? Most copper is refined from sulphide ores. The process includes the following stages: The copper ores are mechanically crushed and ground. The resulting mixture i s treated using flotation with air injection and agitation to leave concentrates containing around 30% copper.

    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. Concentration of the copper(II) sulphate solution by solvent extraction. The very dilute

    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

  • GCSE CHEMISTRY Extraction of Copper Thermal

    The process is called phytomining and it can also be used to extract metals from contaminated land. Brassicas (the cabbage family) can extract metals including cadmium, cobalt and nickel. Copper can also be extracted by displacement from a copper salt solution using scrap iron. Pure copper (99·99%) is needed for good electrical conductivity.

  • Copper Mining and Processing: Processing of Copper Ores

    This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. Heap Leaching is the process of using percolating stone solutions to leach out metals. Heap leaching is very commonly used for low-grade

  • Biological methods of metal extraction Higher Material

    For example, high-grade 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 low-grade copper

  • Extraction Of Copper Mining, Concentration, Smelting

    The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. 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

  • Biological methods of metal extraction Higher

    The solution is called a leachate and the process is called bioleaching. Bioleaching can be used to extract copper metal. It does not need high temperatures, but it produces

  • Extracting copper. Extracting copper.

    Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. The copper produced by this process is 99.99% pure copper. This is similar to the electrolysis that is done in a school lab. Question 2: a) i. The copper mine in picture 4 produces 6 tonnes of copper for every 1000

  • Extraction Copper information provided by Copper

    An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale. The most abundant ores are chalcopyrite and bornite, which contain both copper and

  • Copper Mining and Extraction: Oxide Ores

    The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. The smelting stage gives the name pyroprocessing

  • Copper Mining and Production Processes Explained

    This process is known as SX-EW (solvent extraction/electrowinning). Advantages of these processes are: Much less energy is used than in traditional mining; No waste gases are given off; Low capital investment; Ability to be operated economically on a small scale. It can be used on ore with as little as 0.1% copper for this reason leaching extraction is growing in importance. It is
