Phytomining

2019-11-10 · Phytomining has several stages: Plants are grown in an area with low grade ores where they take in the minerals through their roots. The plants are then burned. The ash is added to water and the minerals dissolve in that water. Electrolysis is then used to extract the metal from the mineral. Phytomining is cheaper than smelting but takes much ...

Bioleaching & Phytomining | Edexcel GCSE Chemistry ...

Bioleaching is a technique that makes use of bacteria to extract metals from metal ores. Some strains of bacteria are capable of breaking down ores to form acidic solutions containing metals ions such as copper (II) The solution is called a leachate which contains significant quantities of metal ions. The ions can then be reduced to the solid ...

Bioleaching Process

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 ...
