Extracting copper from low grade ores via phytomining and bioleaching. How does phytomining work 1. Plants have the ability to take up the copper from the ore and put it in their body tissue 2. You burn the plants 3. The ash contains copper copper taken by electrolysis. Bioleaching.
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.

· Bioleaching is the method of extraction of metals from their ore using living organisms such as bacteria. So, this technique is much cleaner and environmentally friendly than the typical heap leaching method which uses cyanide. This method is very important in extracting metals such as copper, zinc, lead, arsenic, antimony, nickel, etc.
Extracting Metals by Alternative Methods
and so new ways of extracting metals from low grade ores are being developed. A low grade ore has a low concentration of metal. Phytomining and bioleaching are used to extract copper from metal contaminated land and low grade ores. They avoid the more traditional method of digging, moving and disposing of large amounts of rock.
Bioleaching, or microbial ore leaching, is a process used to extract metals from their ores using bacterial micro-organisms. The bacteria feed on nutrients in the minerals, causing the metal to separate from its ore. The metals commonly extracted using this process include gold, silver, zinc, copper, lead, arsenic, antimony, nickel, molybdenum ...
