- Gold is a chemical element; it has the symbol Au (from the Latin word "aurum") and the atomic number 79. In its pure form, it is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal, a group 11 element, and one of the noble metals. It is one of the least reactive chemical elements, being the second-lowest in the reactivity series. It is solid under standard conditions.
Gold often occurs in free elemental (native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as in electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).
Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is insoluble in nitric acid alone, which dissolves silver and base metals, a property long used to refine gold and confirm the presence of gold in metallic substances, giving rise to the term 'acid test'. Gold dissolves in alkaline solutions of cyanide, which are used in mining and electroplating. Gold also dissolves in mercury, forming amalgam alloys, and as the gold acts simply as a solute, this is not a chemical reaction.
A relatively rare element, gold is a precious metal that has been used for coinage, jewelry, and other works of art throughout recorded history. In the past, a gold standard was often implemented as a monetary policy. Gold coins ceased to be minted as a circulating currency in the 1930s, and the world gold standard was abandoned for a fiat currency system after the Nixon shock measures of 1971.
Gold Mining Basics
Finding Gold - Getting Started.
Here are a few of the basics to help you get started.
Do your research.
You don't want to waste a lot of time looking in an area that has no gold. It's hard to find gold in a river that doesn't have any gold. During the winter is an excellent time to do your research. It is one of the most productive things you can do. When looking for a place to prospect you want to look where gold has been found before. If you spend all your time trying to find a new strike you won't find much gold. The old timers did an excellent job of scouring the countryside.
There are many ways to do this research. The Internet is becoming a great source. When researching try to locate a library in the general area you want to prospect. The library will have some excellent resources on, old newspapers, historical publications, old maps, mining reports, and tax records just to name a few. The county recorder is a great place to see what has been claimed and for how long. One of the best things about doing the research is, you get to know the history of the area. The more history you know the more gold you'll find. When you locate a potential area you need to make sure it is open for prospecting. If it's private property or has been claimed, you will save yourself a lot of trouble by getting permission from the owner.
Ok, you've done the research. You've found a potential area, you've got your "gear" and you're now standing on the bank of the river - now what? One of the most basic skills required to recover gold with a pan is "crevicing". Gold being the densest thing in the river, it will end up as low as it possibly can get, and that is the bottom of a crack in the bedrock. Cleaning out these cracks is called crevicing.
There are plenty of other web sites that will talk about the dynamics of the river, pacer geology and such - but it all comes down to, gold is dense. It's very hard to move, and when it finds a low place to get out of the flow of the water, it stays there . Gold only moves when the river is in its flood stage. It takes unbelievable power to move the boulders and gravel to uncover the gold and make it move. Any place in the stream where the power of the water is diminished the gold will drop out. That could be behind a large bedrock outcropping, where the river widens or makes a sharp bend, or where it can drop into a crevice.
There is a lot that comes into play when looking for a potential area to start panning. One of the first things I look at is the general outlay of the river. Where does it get wide? Where does it narrow up? Are there any sharp bends? Is there any exposed bedrock? What type of bedrock, the color of the gravel, the hardness of the rocks, and the placement of the vegetation all play a role in where to look.
Bedrock
When looking at the bedrock, what type is very important. The harder the bedrock, the slower it erodes. For example a granite bedrock is very soft, it erodes quickly and that doesn't allow enough time for the gold to build up.
