The Basics of Successful Gold MiningPart 1

Some people get into gold mining as a getrichquick solution to other problems they have created in their lives. Any person who is giving up or quitting in their personal life hasn''t much chance of succeeding at gold mining! If you are not finding enough gold, you cannot blame the claim, the river, the club you belong to, or anything else.

How Is Gold Processed? Reference.com

Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity, according to Mineweb. Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process.

Silver processing Britannica.com

A process routinely employed in the fire assaying of gold ores is the addition of silver prior to fusion of the ore in order to ensure that the silver content of the final bead is high enough to dissolve. This is called inquartation, and the separating of silver and gold by leaching with nitric acid is referred to as parting.
