Silver processing Britannica
Silver is generally found in the combined state in nature, usually in copper or lead mineralization, and by 2000 bce mining and smelting of silver-bearing lead ores was under way. Lead ores were smelted to obtain an impure lead-silver alloy, which was then fire refined by cupellation. The best-known of the ancient mines were located at the Laurium silver-lead deposit in
How is Silver Mined APMEX®
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. Each cut connects to a central shaft but is kept at a safe vertical distance to avoid collapses. Openings called raises are dug to connect each level. These openings divide the body of ore into blocks. At this point, the Silver mine is ready to
Patio process Wikipedia
25/04/2005· 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. It replaced smelting as the primary method of extracting silver from ore at Spanish colonies in the Americas.

How silver is made material, making, history, used
A method called the cyanide, or heap leach, process has gained acceptance within the mining industry because it is a low-cost way of processing lower-grade silver ores. However, the ores used in this method must have certain characteristics: the silver particles must be small; the silver must react with cyanide solutions; the silver ores must be relatively free of other mineral contaminants
Silver Ore The Mining Processes that Transform Ore into
18/12/2016· The first stage of mining silver involves the crushing the silver ore to about 1-1.5in diameter so as to make the ore porous for the extraction process. Once the ore is crushed it is then mixed with lime (about 3-5 lb. per ton) to create a conducive alkaline conditions for the extractions. The ore is then stacked onto impermeable pads made of asphalt, rubber or plastic to ensure that there is
