In precious metals refining, hydrometallurgy finds application in extracting gold and silver from low-grade ores or secondary sources such as electronic waste or tailings. Through techniques like cyanidation or thiosulfate leaching, gold is leached from the ore into a solution, which is then processed to recover the precious metal.
