Silver is extracted by hydrometallurgy is true.

• Hydrometallurgy is the extraction of a metal from ore by preparing an aqueous solution of a salt of the metal and recovering the metal from the solution.
• The operations usually involved are leaching, or dissolution of the metal or metal compound in water, commonly with additional agents, another being the separation of waste and purification of the leach solution and lastly the precipitation of the metal or one of its pure compounds from the leach solution by chemical or electrolytic means.
• The most common leaching agent is dilute sulphuric acid. Silver is usually extracted from ore by the process of smelting or chemical leaching. Other than gold and silver, copper and zinc are also produced by hydrometallurgy.
