Bacterial leaching is the process where

Bacterial leaching is the process where Bacterial leaching, also known as bioleaching, is a biotechnological process that uses microorganisms to extract metals from ores. A. This statement is incorrect. Metals are not used to kill bacteria in this process; rather, bacteria are used to process metals. B. While some bacteria might interact with copper and gold, this statement does not fully describe the process of leaching, which involves extraction. C. Bacterial action might cause changes in minerals, but changing color is not the primary definition or purpose of bacterial leaching. D. This statement accurately defines bacterial leaching. Bacteria, such as Thiobacillus ferrooxidans*, oxidize metal sulfides, converting insoluble metal compounds into soluble forms that can then be recovered. This method is particularly useful for extracting metals from low-grade ores or mining waste. The final answer is D. bacteria are used to extract metals from waste ore from a mine.
