Question

What are the main potential advantages and disadvantages of using bioleaching based processes for dissolving metals from minerals compared to conventional chemical based processes?

Answer 1

Answew Leaching It is defined as the Substance from a solid added to a liquid the Is the propeets of the metal that we needed dissolved in the liquid. process of Extracting a material, when it is important thing here liguid because the to Extract must be Bio. leaching Bio - leaching is of metals from their hiving organismas. reddered to the ove's by the extraction usage of chemical leaching - This is the conventional of leaching where the metal's con be I from the mineral's by dissolving the in a suitable Solvent- method Sepeected mineral's | Advantages of Bio-leaching over chemical leaching - The method is simplor, cheaper to operate and - maintain . 1-) This method is used to extract metal's from ove's that all too pour for other kechnologie's. 1) Bio- leachine is environmental reindly. a) Bio-leachine ig used for all process will drastically reduce the amount of green house ga

- This method is used to collect metal's from waste and drainage, it's not applicable by our traditional method. - No poisonou's 502 emission's as in chemical I leaching 1-) It is idealy suiked for developing countries. D is advantage's of Bio-leaching over chemical heaching - This process is Very slow. - Enormous amount of heat con be produced I from the process and it on kill the Bacteria - Unlike our chemical leaching, Bis-leaching can't be quickly stopped. - Toxic chemical's are also some time's be Produced - Environmentaly and Economicaly, Bio- leachine is behind the chemical leaching.
