Silver Mining Process . Silver is mined using a number of processes. One of the most common processes of extracting silver metal for the ore is the heap leach or cyanide process. The process is most popular with many miners because it is low cost, especially when processing low-grade ores.
Waste rock and tailings from mercury mining, and other extraction processes where mercury is uncovered, can still contain small or large amounts of the toxic substance. Mercury that is not processed or claimed during mining and ore processing can make its way into the environment if the mining waste is not stored properly.
In modern times though, mining for gold is a much more intensive, yet sophisticated process. Most surface, or alluvial gold has been found, which is why gold is mainly mined from the earth today. Most surface, or alluvial gold has been found, which is why gold is mainly mined from the earth today.

6.1 Process Overview 6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.
Equipment Used For Firing/Smelting Ore. Furnace Or Oven For Firing/Smelting: It must heat to 1950 degrees F for gold and 2100 degrees F for silver.A muffle furnace is best. It fires to about 2300 degrees F and the ingredients can be easily added to the ore while firing.
The patio process is a process for extracting silver from ore. The process was invented by Bartolomé de Medina in Pachuca, Mexico, in 1554.  The patio process was the first process to use mercury amalgamation to recover silver from ore.
You probably know that silver is a metal that's mined and then somehow refined to form the pure coins and bars we trade as bullion, but would you like to know a little more about that process? We've found an excellent little YouTube excerpt by the Discovery Channel on the process of mining and refining silver.
Several processes can then be used to separate the gold from the ore. The most common techniques in the United States use cyanide in various ways. In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore.
lead reduction smelting process. The only difference between these three things is one of scale. To quote Agricola (pp. 220-223): "The method of assaying ore used by mining people, differs from smelting only by the small amount of material used…. Both processes, however, are carried out in …
