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.

What are the advantages of using bioleaching to extract copper?
It is environmentally friendly, provides jobs and is very economical.
What are disadvantages associated with using copper sulfate in hemoglobin?
yes
How do you extract copper using dilute acid?
If you want to extract copper using dilute acid you must use sulphuric dilute acid. Pour it into a container and add some copper oxide (it's powder, I'm not sure if that's it's name) then take another container and put some filter paper on it and pour the mixture into that. It should look blue. Then add some filings into it and they should turn pink.
What are the benefits of using copper washers?
Using copper washers as opposed to using aluminum aren't to much more beneficial except for the fact that copper is more reusable. On the down side copper is more expensive.
