How bioleaching works?
it means they suck your blood
What are the advantages of using bioleaching?

I have to make a storyboard of six to eight boxes explaining the processes of bioleaching. I am only in year nine so what is bioleaching in simple terms?
Shortly, bioleaching is a method of separation of metals from ores using living organisms; for the beginning read the text from the link below.
How does bioleaching work?
Bioleaching uses bacterial microorganisms to extract precious metals, such as gold, from ore in which it is embedded. Bioleaching works because of how special microorganisms act on mineral deposits. They are a catalyst to speed up natural processes inside ore.
What are the methods of extracting copper called?
The newest method is bioleaching.
Why is bioleaching and phytomining important?
They are cheaper alternatives to processes such as electrolysis and are better for the environment
How is bioleaching environment friendly?
bioleaching is that process which is now a days being used on world scale for removal of waste which in the form of minerals like low graded ore of gole ,silver.uranium to get rid of pollution by using microorganism like bacteria & fungi.
What are the advantages of using bioleaching to extract copper?
It is environmentally friendly, provides jobs and is very economical.
Why would an increase in bioleaching not happen?
If large new deposits of high-grade ore are discovered.
What are the bad points of bioleaching?
It is very slow, toxic chemicals can be produced in the process and it is not always feasible.
What are the disadvantages of using bioleaching to extract copper?
Some disadvantages associated with bioleaching are:not economical: the bacterial leaching process is very slow compared to smelting. This brings in less profit as well as introducing a significant delay in cash flow for new plants.not environmental: Toxic chemicals are sometimes produced in the process. Sulfuric acid and H+ ions formed can leak into the ground and surface water turning it acidic, causing environmental damage. Heavy ions such as iron, zinc, and arsenic leak during acid mine drainage. When the pH of this solution rises, as a result of dilution by fresh water, these ions precipitate, forming "Yellow Boy" pollution. For these reasons, setup of bioleaching must be carefully planned, since the process can lead to biosafety failure.Currently it is more economical to smelt copper ore rather than to use bioleaching, since the concentration of copper in its ore is generally quite high. The profit obtained from the speed and yield of smelting justifies its cost. However, the concentration of gold in its ore is generally very low. The cheaper cost of bacterial leaching in this case outweighs the time it takes to extract the metal.
How do you extract copper from a low grade ore?
Through bioleaching, thermal decomposition, displacement, phytomining & electrolysis.
