Lead Nitrate Leaching Copper Gold Silver

  • how silver is made, making, history, used

    silver is rarely found alone, but mostly in ores which also contain lead, copper, gold, and other metals which may be commercially valuable. silver emerges as a byproduct of processing these metals. to recover silver from zinc bearing ores, the parkes process is used. in this method, the ore is heated until it becomes molten.
