Silver Ore - The Mining Processes that Transform Ore into

Dec 18, 2016· Silver is quite different from gold because it is nearly always found within ores that require specialized mining techniques to extract. Silver ore is one of the most important resources on Earth. After processing and refining silver is used for countless industrial uses today. The Main Sources and Uses for Silver Silver is []

Getting silver from Galena

May 20, 2010· This entails mixing the galena powder with sodium carbonate and salt, under an oxygen lance in a crucible. This way any sulfur dioxide is absorbed by the carbonate. This is a patented known process and would be much easier and safer than regular smelting. I think at around 900 C - I have a hobby furnace capable of upto 1200 C

solution to separate gold from galena

Gold processing from galena. There is an old method, called the Parkes process, which was used to separate silver (and gold) from lead The argentiferous galena is first reduced to metallic lead, Then zinc is added to the molten lead, The silver is much more soluble in

Extracting Gold | HowStuffWorks

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
