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

Phytoming 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 are

Bioleaching Certain bacteria can break down low-grade ores to produce an acidic solution containing copper ions. The solution is called a leachate and the process is called bioleaching .

Phytomining is the production of a `crop' of a metal by growing high-biomass plants that accumulate high metal concentrations. Some of these plants are natural hyperaccumulators, and in others the property can be induced. Pioneering experiments in this field might lead to a `green' alternative to existing, environmentally destructive, opencast

Unlike traditional excavation, phytomining is dependent on growing conditions such as the weather, altitude and soil quality. A bad growing season could wipe out an entire crop of metal-producing plants, and if global climate change alters weather patterns, the risks associated with establishing a long-term phytomining industry in an area increase.

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.

When they do this, they produce a copper-rich solution, called a leachate. We can extract the copper from this with electrolysis or by a displacement reaction with scrap iron; Cu 2+ (aq) + Fe(s) → Cu(s) + Fe 2+ (aq). Like phytomining, bioleaching is a useful method for extracting metals from low-grade ores.

Bioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals.
