Bioleaching is the extraction of metals from their ores through the use of living organisms. This is much cleaner than the traditional heap leaching using cyanide .  Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum ...
The economics of phytomining basically depends on the metal content in the soil, metal uptake by the plant, plant biomass and most importantly the metal price. Metal prices are subjected to cyclical variation, and a low current value for a given metal should not preclude consideration of its extraction by phytomining.

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.
Bioleaching and Phytomining Extraction of Copper by . Extraction of Copper from Ores Phytoming and Bioleaching Phytomining How It works This is one way of extracting copper from low grade ores which are less than 1%. Get Price. Extracting metals from rocks- Learn Chemistry.
phytomining. Bioleaching Advantages: Simpler process than smelting which requires fewer expert staff to operate, reducing costs. Produces less sulphur dioxide emissions than smelting. Used to extract copper from low grade ores (ores containing a small percentage of metal) which are un suitable for smelting. Disadvantages:
Purification of Copper by Electrolysis (extraction from ore above) The impure copper from a smelter is cast into a block to form the positive anode. The cathode is made of previously purified copper. These are dipped into an electrolyte of copper(II) sulphate solution.
Sep 03, 2013· Why is phytomining used to extract copper? I know that phytominging is when you plant certain plants on low grade copper ores. The plants then absorb the copper compounds which means you can then burn the plants to be left with the ash which contains the copper ores.
The Extraction of Copper by Thermal Decomposition, Bioleaching and Phytomining. Extracting Copper from Malachite - GCSE Science - Marked… Chemistry Extracting Copper from Malachite We extracted Copper from Malachite using a displacement reaction. Although electrolysis can also.
but they are still used because copper is so valuable. 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

Some plants absorb copper compounds through their roots. They concentrate these compounds as a result of this. The plants can be burned to produce an ash that contains the copper compounds. This method of extraction is called phytomining. Advantages of phytomining Phytomining is …
Phytomining requires the use of cyanide once only, over a timeframe of minutes, where the purpose of the chemical is to promote sufficient solubility for uptake. During phytomining the irrigation of chemical is designed to mitigate the potential for leaching of the chemical and gold out of the root zone.
Bioleaching uses bacterial microorganisms to extract precious metals, such as gold, from ore in which it is embedded. As an alternative to smelting or roasting, miners use bioleaching when there are lower concentrations of metal in ore and they need an efficient, environmentally responsible method.
