Phytoextraction and bioleaching (bacterial) are two relatively new methods of extracting metals that rely on biological processes; Both of these methods avoid the significant environmental damage caused by the more traditional methods of mining; Traditional mining involves a great deal of digging, moving and disposing of large amounts of rock
Study with Quizlet and memorise flashcards containing terms like Why are phytomining and bioleaching used?, Stages of phytomining, Disadvantages of phytomining and others.
Microbial ore leaching (bioleaching) is the process of extracting metals from ores with the use of microorganisms. This method is used to recover many different precious metals like copper, lead, zinc, gold, silver, and nickel.
Another way of extracting low grade copper from its ores economically: (bioleaching) — In bioleaching, bacteria are mixed with the low - grade ore. — The bacteria, carry out chemical …
Bioleaching - advantages. Simpler process than smelting and requires fewer expert staff to operate, reducing costs. Produces lower sulfur dioxide emissions than smelting. Phytomining - advantages. Decontaminates polluted ground. Carbon dioxide emissions are lower than for smelting.
Common alternative methods of metal extraction include leaching, bioleaching, and electrowinning. →How does leaching work in metal extraction? Leaching involves dissolving metal ions from the ore using a suitable solvent, such as an acid.

Another way of extracting low grade copper from its ores economically: (bioleaching) — In bioleaching, bacteria are mixed with the low - grade ore. — The bacteria, carry out chemical reactions and they produce a solution, called leachate. — A leachate, contains the desired metal compound. Extraction after either phytomining or 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.
