Bacterial leaching technique
Thread Content
I heard that bacterial leaching technology can completely extract metallic copper from copper oxide ore. I would like to ask if this is feasible
There’s a lot of information about bacterial leaching on forums; you can check it out.
Is there any process for bacterial sulfur removal?
Bacterial leaching is generally applied to copper sulfide ores; for oxidized ores, acid leaching can be used directly. Bacteria are typically used to decompose copper sulfide or pyrite, and this decomposition process produces sulfuric acid. The original poster can check out more relevant materials.
1# dxty: If the bacterial leaching method is feasible, it is not suitable to use due to the high oxidation costs associated with the mixing tank; therefore, some pyrite should be added during pile construction. The amount of pyrite to be added needs to be determined through experiments. In this way, the acid produced by the bacteria oxidizing the pyrite can be used to meet the acid consumption requirements of the oxides, while the resulting ferric ions and acid facilitate the leaching of copper.
Copper oxide? It’s usually sulfide ores, right?
Bacteria leach copper by using sulfur-oxidizing bacteria to convert sulfur into sulfuric acid, thereby leaching the copper; this process is quite mature

Bacterial leaching includes oxidative leaching and reductive leaching; for copper ores, oxidative leaching is generally used, while it is applied to sulfide ores as well, but the permeability still needs to be considered. 1# dxty
