  • Arrastras. Historic Gold Mining Method for Processing Ore

    An arrastra, also known as a Mexican Rastra, was a primitive method used by early miners to process gold and silver ores. It was introduced to the new world by the Spanish in the 1500s. They were used throughout the world, often at remote locations where other processing methods were not feasible.
