Bioleaching Certain bacteria can break down lowgrade 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 highbiomass 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 ...
Jul 25, 2018· Phytomining describes the production of a metal crop by using highbiomass plants, which are plants that produce energy or a usable resource when burned. Phytominers cultivate crops of a specific plant species with high concentrations of a desired metal, harvest the plant and deliver it to a furnace to burn and gather its bioore.

Bioleaching, or microbial ore leaching, is a process used to extract metals from their ores using bacterial microorganisms. 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 ...
Bioleaching. Some bacteria can live by using the energy of the bond between sulfur and copper. This separates the metal from the ore and is called bioleaching. It has the advantage that it is very energy efficient typically using only 30% to 50 % of the traditional method. It has the disadvantage that it is very slow. Phytomining.
