Explanation
The extraction of metals from their ores through the use of living organisms is known as Bioleaching.
Bioleaching is a cleaner method than traditional heap leaching using cyanide. It is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt. So the correct answer is D: Bioleaching.
