Working near the mines of Pachuca, not far from Mexico City, Medina adapted a method he apparently learned of in Spain from visiting Germans. In 1554, he developed what later became known as the patio process, an open-air system of beneficiation that mixed finely ground silver ore with mercury and other reagents. These were stirred periodically ...
