Finding Gold is a very difficult task, it involves hours of work and a lot of patience, but in the end, it is highly rewarding. Buying it, is an option but where’s the fun in that? Gold prospecting has now become an adventure that many people get involved in every year. And not just to make a fortune but also having a quality time that includes hiking with their pals. This precious metal has continued to climb the economic ladder; therefore, it is a tempting time to own some of it because it may able you to make large profits just by sitting at your home.
Nowadays, there are many ways that people use to find gold, but one of the most common and easiest ways to do such a task is by using a metal detector. Metal Detectors are the new way to ease your search for gold. Moreover, there are specially made metal detectors that can detect gold. When you own a metal detector you have a world to discover that is unseen and hidden from the naked eye. However, the powers of a metal detector are still limited and you shall not have any high expectations from a basic metal detector.
Can a Simple Metal Detector Detect Gold?
The answer to this is positive because gold like any other metal compound can be found with the help of a simple metal detector. Moreover, you can also optimize it to specifically finding gold in certain areas.
Why aren’t all Metal Detectors Good for Finding Gold?
To answer this question we must first understand how a metal detector works. A metal detector works by producing a magnetic field which then responds to the hidden objects in the ground. The response that we receive on our metal detector is a culmination of a large number of factors such as; the frequency of the detector, the size of the object and its depth, the conductivity of the hidden materials and the type of soil or ground including much more. All of these things have an important role in finding the hidden materials that is why not all metal detectors can find gold consistently.
Metal detectors that are designed with a low frequency are not suitable for finding gold because of the small size and its low conductivity. As compared to them, high-frequency metal detectors are better because gold has higher conductivity with high-frequency waves than lowers ones and they can more accurately find small traces of gold.
What are the Best Types of Metal Detectors to Find Gold?
Two of the most expensive kinds of metal detectors are multi-frequency or PI-type detectors which are best for finding gold. They may be expensive, but the features that accompany them are worth the big bucks. Usually, the areas where gold is found have very high mineralization which means that a lot of minerals with almost the same conductivity will be present. So it will be hard to get the property conductivity of metal which will allow proper metal detection. Machines that are specifically designed to search for gold will be able to easily overcome this barrier of mineralization and accurately locate gold.
How do Metal Detectors Detect Gold?
Understanding how this tool stands out in finding gold will help you understand the basic science behind metal detectors. Put very simply, a metal detector works by transmitting an electromagnetic field into the ground. It then analyzes the return signal. The electromagnetic field induces a loop of electrical currents called eddy currents.
Eddy currents make their magnetic field which the detector receives and then analyzes. But when gold detectors are in question they take the whole process up a notch by measuring inductance and conductivity. Inductance is defined as the number of eddy currents in this scenario and conductivity refers to the ease of flow of these currents. Then by measuring the size of the eddy currents and the speed at which they travel, gold detectors derive a time constant for the target.
Time constants can vary considerably between different metals, for example, aluminum tends to have shorter time constants as compared to gold, steel, iron, and other ferrous metals. Additionally, some have even longer time constants. Gold detectors can easily be calibrated to only pick up targets that fall within the middle range; however, this may not be effective as there are many other detrimental factors that we have been mentioned above.
Now that we have answered some of the most compelling questions about metal detectors and their effectiveness lets learn something about prospecting of gold to furthermore explore this fortunate and adventurous journey.
What are the Best Places for Gold Prospecting in the World?
The most prized possession of mankind is found in many countries of the world and that too in great abundance, but some of the countries have been extraordinarily blessed with excess gold. So, if you’re looking to make some real cash then these are the best places to go to!
- The Super Pit (Kalgoorlie, Western Australia)
- Gold Country (California, United States)
- Carlin Trend (Nevada, US)
- Yanacocha (Peru)
- OyuTolgoi (South Gobi Desert, Mongolia)
- South Deep (Near Johannesburg, South Africa)
What is the Best Season for Gold Prospecting in the World?
- Post-Snow Melt, as the snow melts it tends to break up the gravel in the mountains that brings down the materials into the rivers and streams as the weather begins to get a little warmer.
- After Heavy Rainfall and flooding, as heavy rain pours down on the mountains, it takes off the top layers of soil, bringing down a large number of materials down to the rivers. As they come down many gemstones and often gold accompanies them.
- Droughts, as opposed to our previous suggestions this is a 360-degree turn, but as the water disappears, from some areas, you can access places which you wouldn’t be able to do so due to water. The best place to look for would be black sand as it will easily reveal the gold.
With the right research, equipment, method, and location you are set for an expedition that will allow you to discover Mother Nature and make you a large sum of money if you are lucky enough. Finding gold using a metal detector may be the most futuristic method right now, but it does not guarantee you a wealthy adventure although it can still be worthwhile.
