Cover the ore mixture with the remaining soda ash the borax and the silicon sand. Place in the furnace and put on high heat 2100 degree F. It takes about 2 hours or longer so don .
The patio process is a process for extracting silver from ore. The process was invented by Bartolom de Medina in Pachuca Mexico in 1554. The patio process was the first process to use mercury amalgamation to recover silver from ore. It replaced smelting as the primary method of extracting silver from ore at Spanish colonies in the Americas.
