How To Identify Gold In Rocks? Cutting Ore Samples, Mineral Identification, Finding Free Gold!

Many people hunt for gold rocks for a myriad of reasons. T

he monetary and ornamental value of gold minerals surpasses others.

The process of the rocks formation affects the location of the stones.

In this article, we shall learn about the characteristics and chemical components of the rocks containing gold.

How Do You Remove Gold From Rocks

Put the rock in a metal container then swing a sledgehammer down onto it. Continue to strike the rock with your sledgehammer until its broken up into small pebble-sized pieces. You dont need to grind your pebbles into a powder when youre using mercury sulfide to extract the gold. See also what is the pacific plate

Has Granite Have Gold In It

Accordingly to a recent paper by Prof. George P. Merrill, Curator of the Department of Geology of the U. S. National Museum, Washington, upon An Occurrence of Free Gold in Granite, describes an interesting instance of the dissemination of this noble metal in the substance of granite of normal composition believed to be from Sonora, Mexico.

Professor George P. Merril submitted a number of thin sections of the rock to examination and with the aid of the microscope gave confirmatory evidence.

The goelogist, found the gold in small scales, rarely exceeding a millimeter in diameter, distributed through the scales of mica and apparently enclosed in both the feldspar and quartz granules.

Where Are Utahs Gold Placers

Utahs placers are usually associated with areas of igneous rocks. Gold-bearing solutions deposited gold within the surrounding rock formations . As these gold-bearing rocks are eroded, the free gold is deposited and concentrated into placer deposits. Finding gold is possible in any stream or river that crosses a gold-mineralized area. However, since the known placer deposits have been worked and reworked for over 100 years, the chance of finding large concentrations of gold in Utahs streams is small.

Utah placers have been reported in the following areas:

  • Abajo Mountains Along Johnson and Recapture Creeks.
  • Oquirrh Mountains, Bingham Canyon Was the largest gold placer in Utah. The original topography has been altered by the open-pit mining operations.
  • Colorado River From the mouth of the Dolores River south to the Amasa Back bend west of Moab. Most placers were from the Dirty Devil River south to the Utah-Arizona border and are now under Lake Powell.
  • Green River From Flaming Gorge Reservoir down to Horseshoe Bend.
  • Henry Mountains On the east flanks of Mt. Ellen in Crescent Creek and Mt. Pennell along Straight Creek.
  • House Range In Amasa Valley and Miller Canyon.
  • La Sal Mountains In glacial deposits and streams of Miners Basin, Wilson Mesa, Bald Mesa, and around North Mountain.
  • San Juan River From the mouth of Montezuma Creek west to Lake Powell.
  • Fools Gold

    Pyrite crystals commonly form pyritohedrons with striations on the crystal faces.

    What Is Known As Fools Gold

    Gold var. Electrum

    Fools gold is the name given to pyrite. It got the name because it is equal to nothing in value even though it has a look that makes it look like gold to foolish people. There are a few ways you can use to decipher if it is pyrite or gold. There are a few tests that can help you ascertain if you are dealing with fools gold or not. The first test of difference is the presence of tarnish on pyrite. This is because most of the specimens of pyrite from nature will always have some measure of tarnish on its surface, small flakes or Nuggets of gold are often untarnished and bright.

    In the aspect of color, pyrite comes in a brassy color while gold has a yellow to golden color. A number of the native gold around usually comes in an alloy of silver. If the silver content is quite high, the specimen is bound to have a whitish-yellow coloration. In terms of shape, Pyrite is generally gotten in angular pieces and they tend to have faces of the cube. Golden particles found in streams for instance always come in rounded edges. There is however some crystalline gold that shows traits of pyrite as well.

    The third destructive test has to do with its ductility. Gold is known to be very ductile and this means that a small piece of gold will dent with a small pressure from a pin. Pyrites, on the other hand, will resist or even break the pressure. The final test is sectility. Gold can be cut using a sharp pocket knife while particles cant be cut.

    What Is Placer Gold

    Placer Gold

    Placer gold or natural nuggets are large gold deposits often found in dry streambeds or riverbeds. These nuggets are usually found many miles away from their place of origin. Therefore, finding placer gold does not necessarily mean that you just found the gold mine.

    You can find placer gold by using a metal detector and panning techniques. The metal detector helps to identify the location of the placer gold in the dry creek bed. However, sometimes the gold nugget is of small size and mixed with dry soil or sand. Therefore, you can try the panning method to extract gold from the mixture.

    Moreover, you should know that the panning technique is the same globally. For instance, gold panning in Arizona is the same method as used for gold panning in Colorado.

    Break Them With A Sledgehammer

    This is where your sledgehammer comes in. Lift it and bring it down on the rocks. Hit them really hard. Keep hitting them in this manner until they become tiny pebbles.

    If you can get a power hammer, you will have an easier and faster job of breaking the rocks.

    I would like you to know of the option of lifting a very heavy object over them and letting go. But this is not efficient.

    However, if you are a serious prospector of gold, consider buying a crushing machine. It will save you time and effort.

    How Do I Identify Gold When Buying

    One thing about genuine gold jewelry is that it comes stamped with a hallmark indicating its authenticity. This is however not a foolproof strategy to determine the authenticity of the gold. Also, we cannot easily identify jewelry stamps or what they mean. There are however different ways to confirm if your jewelry is real gold or not. These signs may not be easily seen by an untrained eye, but the following steps should help you out.

    First, ensure that you carry out a visual inspection. You will need to see if it has any discoloration or if it is a base metal that is shining via the coat. If this is the case you may be looking at jewelry that is simply gold plated. There is also nothing wrong with purchasing gold plated jewelry but the thing is that it is not usually solid gold and as such, it should be labeled rightly. Real gold will also not discolor. The last thing you should look out for is weight. The reason for this is that solid gold is often quite dense and heavier than fake gold. You may ask a jeweler to inspect a professional opinion.

    The second thing to do is to look out for the Gold Hallmark. The hallmark is simply a stamp that exists on the piece of jewelry which informs the buyer of what it is that they are purchasing. In several countries, jewelers must indicate when gold is genuine. They also make it compulsory to state the karat of the gold. If this is not enforced, it will be quite difficult to determine the karat of the gold.

    Is There Gold In Every River

    ROCKS to GOLD – How to Do It | ask Jeff Williams

    Every river in the world contains gold. However some rivers contain so little gold that one could pan and sieve for years and not find even one small flake. After rigorous chemical analyses rocks that are found to contain gold in levels where only one part in one million is gold can be professionally mined.

    How Do You Extract Gold From Rocks At Home

  • Wear Protective Gear. The act of crushing rocks is dangerous.
  • Use a Metal Container. Take the rocks you want to crush and put them into a container.
  • Break Them with a Sledgehammer. This is where your sledgehammer comes in.
  • Pulverize the Rocks.
  • Put the Rocks inside the Mining Pan.
  • Shake to Reveal the Gold.
  • How Does Gold Get Into Rivers

    Answer 1: Gold is concentrated in certain geothermal solution formed when magma is injected into water bearing rocks. Then because of its large density gold gets transported by streams and concentrated into what are called placer deposits. These are fluvial sediments that occur along the banks of streams and rivers.

    Not Just Rocks But Minerals Can Contain Gold

    Calaverite and sylvanite are minerals that contain gold. There chemical formula makeup includes the element Au. Sylvanite will contain around 34% gold, calaverite will contain around 43%.

    These two minerals are almost the same in chemical composition. What separates them as two different minerals is the content of silver. If there is less than a little over 13% of silver, replaced by gold, then it is considered calaverite.

    Many other minerals can contain amounts of gold in them. Though they may not be part of the chemical makeup of the mineral, they may present in the mineral as an impurity.

    Pyrite is a good example of this. Though pyrite is often called fools gold, it can actually contain gold. At times, if the contents of gold is high enough in pyrite, it will be extracted. Keep in mind the ratio of gold to current price of gold, as your cost to extract may exceed your profit!

    Pyrite is a wonderful mineral that many people especially kids love to collect. I have written a great article on pyrite All About Pyrite including information and pictures.

    How Do You Know That A Rock Has Gold In It?

    You can scratch a rock against a piece of unglazed ceramic like the back of a kitchen tile to see if it has gold in it. Genuine gold leaves a gold streak while fools gold leaves a greenish-black one.

    Gold isnt attracted by a magnet, while fools gold is because it has a high iron content. If you put a rare earth magnet next to the rock and nothing happens, chances are it contains gold.

    Also, close inspection of the rock with a jewelers loupe will show a distinct yellow color and non-crystalline structure in the case of genuine gold. Iron pyrite or fools gold has a pronounced crystalline structure.

    What Types Of Rocks And Minerals Are Associated With Gold

    There are a number of different rocks and minerals that are found near gold or are part of gold deposits. By starting your search for these rocks and minerals, you are essentially looking for a broader footprint of where the gold might be.

  • Magnesium Ferric: This is a type of mineral that can help you find the gold. They are usually dark colored and often will have black or red tinges on the sides. This type of mineral is usually a big clue that gold may be nearby because of its association with gold.
  • Chalcopyrite: Otherwise known as Fools Gold this is the stuff of old Western movies and other legends where the hearty gold miners were subsequently fooled into thinking that this rock was actually gold itself. However, Fools Gold is often found near actual gold deposits and serves as a sign that real gold is close at hand. You can often find this pyrite in creek beds while panning for gold. If you find it, take heart that while it is not real gold, you may actually find gold nearby.
  • Iron, Lead, Pyrite and Magnetite: These are heavier metals and minerals that are often associated with the location of gold deposits. This is because such metals, rocks and minerals are formed around gold veins which then break off and spread out away from the gold itself. Such heavy minerals and metals offer a clue that gold just may be around the corner.
  • Three Rocks That Contain Gold

    What does gold look like in rocks_ Gold bearing rock identification.

    For thousands of years people have been chasing after gold. Finding gold has been a part of life for many civilizations for centuries. Rocks are obviously where you find gold, but many do not know much about rocks to know which rocks might contain gold.

    Gold is contained within the three main rock types Sedimentary rock, metamorphic rock, and igneous rock. All three rock types are known to contain some amounts of gold. Sedimentary rocks are often thought of containing the most gold.

    In many cases gold will end up in rocks by the hydrothermal process. Cracks and openings in rocks were filled with heated ground water. This hot liquid was pushed from below into these cracks filling them with its contents, including gold.

    You need to know something about how gold deposits occur to understand which rocks to look for when prospecting. Alluvial deposits are made by water running over rocks in rivers and streams, while gold veins or reefs are deposits of gold left by geological processes in large bodies of rock. The former are secondary deposits, while the latter veins and reefs are primary.

    Five rocks to look for when gold prospecting are quartz, granite, basalt, schist, and slate. Gold is deposited in them through volcanic hydrothermal activity or rainwater solutions containing minerals and heavy metals like gold. Gold drops out of the solution and is deposited in cracks and crevices.

    Its hard to find gold in significant quantities, but you can improve your chances by knowing where to look and what to look for. Panning for gold in a mountain creek or on a sandbar in a river can be exciting when you catch that first bright glint in the sunlight.

    This article explains what to look for in rocks when prospecting for gold, the five kinds of rocks commonly associated with gold, and how to tell if a rock has gold in it.
