How the process of mining for silver works Fraimed

The process is attributed to a mining specialist Bartolomé de Medina who was the first to use a silver amalgamation with mercury to extract silver. De Medina’ s technique involved mixing the ore with mercury and strong brine. This formed a mercury silver amalgam from which semi-pure silver could be obtained by distilling off the mercury.
