    Plants absorb metal ions through their roots in a process called Phytomining It removes toxic metals from contaminated soil – around old mines for example In the future, when supplies ofPhytoextraction (phytomining) It is a slow process Bioleaching Certain bacteria can break down lowgrade ores to produce an acidic solution containing copper ions The solution is calledBiological methods of metal extraction Higher MaterialPhytoming and Bioleaching Extraction of Copper from Ores Bioleaching Advantages We can use waste ores, reducing the impact of mining on the environment Energy efficient, using almost half as much energy as traditional extraction No gases that will harm the environment areBioleaching and Phytomining Extraction of Copper by

  • GCSE CHEMISTRY Extraction of Copper Thermal

    Extraction of Copper Copper is sometimes found as native metal Copper ores include copper(II) oxide and copper(II) sulfide Copper(II) oxide can be reduced by reaction with carbon Some copper ores may contain only small amounts of copper These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable Bioleaching and phytomining areFinite reserves of copper ores are becoming scarce and new ways of extracting copper from lowgrade ores include phytomining, and bioleaching Low grade ores only contain small concentrations of copper and would not normally be considered economic to mine and process, as would waste material from processing high grade copper orespurification of copper by electrolysis metal extractionPhytomining and Bioleaching Metal ores are a finite resource which are in limited supply New methods of copper extraction exploit waste ores and low grade ores Phytomining involves growing plants on top of low grade ores The plants absorb copper ions through their roots The plants are then burnt to ashes containing copper ions These ions are leached from the ash using sulfuric acid ScrapPhytomining and Bioleaching GCSE Triple Award Revision

  • what is phytomining and bioleaching

    Like phytomining, bioleaching is a useful method for extracting metals from lowgrade ores This is particularly important for copper, where highgrade ores are increasingly rare It also uses less energy than smelting However, some of the chemicals produced in the process are harmful, and the process is relatively slow and expensiveThe process of phytomining of copper einfach the extraction of copper by thermal decomposition, bioleaching and phytomining what are the disadvantages to phytomining it is a long process and the burning of plants releases pollutionin the form of carbon dioxide Read More The process of phytomining of copper Phytomining is used to extract copper from soil containing its ore 1Copper Phytomining ExtractionPhytomining and Bioleaching Metal ores are a finite resource which are in limited supply New methods of copper extraction exploit waste ores and low grade ores Phytomining involves growing plants on top of low grade ores The plants absorb copper ions through their roots The plants are then burnt to ashes containing copper ions These ions are leached from the ash using sulfuric acid ScrapPhytomining and Bioleaching GCSE Triple Award
