The process of mining raw silver and minting rounds
It involved mixing silver ore with salt and other mineral compounds, then using tethered mules to churn the mixture. It was followed by the "von Patera process," which used heat to remove silver chloride from ore. Silver mining was brought to North America in the eighteenth century where several additional methods of mining were developed.

Patio Process. The earliest method of extraction was a method developed in the Mexican mines in the mid 1500s and familiar to the miners at ia City, the Patio Process. This method of processing the rocks to extract the silver was slow, did not recover all the silver, and did not use the added reagents as efficiently as possible.
