    Phytomining and Bioleaching GCSE Triple Award Revision

    Phytomining 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. Scrap

    Evaluate the Use of Phytomining and Bioleaching in Metal

    Like phytomining, bioleaching is a useful method for extracting metals from low-grade ores. This is particularly important for copper, where high-grade 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 expensive.

    Phytomining & Bioleaching By Lucy Patterson (Sophie's Sibling)

    Bioleaching can extract metals from ores that are too poor for other technologies which means less waste. Toxic chemicals are also sometimes produced in this process. RECAP! BIOLEACHING AND PHYTOMINING ARE BOTH METHODS OF WHAT? (extraction of metal, in this case copper) WHERE DOES PHYTOMINING EXTRACT COPPER FROM? (the ash of burnt plants) WHERE DOES BIOLEACHING EXTRACT

    GCSE CHEMISTRY Extraction of Copper Thermal

    Bioleaching and phytomining are increasingly used to extract copper from low grade ores (see below). The traditional method of extraction is to heat the copper sulfide. Copper(II) sulfide gives copper and sulfur dioxide during thermal decomposition. Thermal decomposition means that the compound breaks down into other substances when it is heated.

    Extracting Metals by Alternative Methods

    Copper extracted from its ore by bioleaching or phytomining is impure. In order to purify the copper, it must be dissolved in an acid, such as sulfuric acid, then electrolysis is carried out. The impure copper from the copper sulfate solution is attracted to the pure copper negative electrode. Titanium is used for the positive electrode. Copper can also be extracted from solutions of copper
