The ManufacturingProcess. Silver was first obtained in sixteenth-century Mexico by a method called the patio process. It involved mixing silver ore, salt, copper sulphide, and water. The resultant silver chloride was then picked up by adding mercury. This inefficient method was superseded by the von Patera process.

The silver that remained at the bottom of the cupel was run-off and solidified into blocks. Since lead was also valuable, it was recovered by placing the litharge (lead oxide) remaining from the cupellation process into yet a third furnace and heated to 250 degC and air was blown through it. The lead was run-off and formed into rods.

Silver also occurs alongside lead, copper and zinc ores, which is why nearly 50% of mined Silver today is obtained when processing other kinds of ore. Silver is separated from this ore using a chemical process known as smelting. To begin a new Silver mine, a system of multi-layered crosscuts are made.
Environmental Impact of Mining Silver. Mining silver, or any mineral in general, can greatly impact our environment. For one, it causes lots of erosion. It also contaminates groundwater, soil and surface water by using chemicals from the mining process. Plus, mining contributes to the formation of sinkholes and loss of biodiversity.

The ancient process of refining gold has already been described under METALLURGY (which see). Most of the Bible references are to the refining of silver (Proverbs 25:4 Zechariah 13:9 Isaiah 48:10). The silver used by the ancients was probably obtained by smelting lead sulfide ore, rich in silver (argentiferous galena).

The patio process is a process for extracting silver from ore.The process, which uses mercury amalgamation to recover silver from ore, was reportedly invented by Bartolomé de Medina in Pachuca, Mexico, in 1554. It replaced smelting as the primary method of extracting silver from ore at Spanish colonies in the Americas.

· Silver Mining Stocks: Silver mining stocks can offer indirect exposure to silver prices. These stocks tend to be leveraged plays on silver prices, owing to the high fixed costs of extracting the metal. Mining stocks are considerably more liquid than physical silver as they can be bought and sold during market trading hours.
Silver processing - Silver processing - The metal and its alloys: Even silver that has been fully work-hardened, either by rolling or forging, gradually recrystallizes, even at room temperature. This greatly softens the metal, making it susceptible to scratching and marring. To maintain hardness, therefore, other metals are added to form alloys that are harder, stronger, and less prone to fatigue.
