How to Tell Fools Gold From Real Gold
Pyrites or Iron Pyrites, also known as “Fool’s gold“, is a mineral that has historically been confused with gold because of its similar color and shape. But despite the similarities in appearance to real gold, it can be precisely distinguished from it if you know what to look for.
First of all, the streak of the two minerals is different. “Streak” refers to the color of a mineral’s powder. The color of a mineral’s powder can be tested by rubbing the mineral on a covering of hard white porcelain. The color of the residual streak indicates the contents of the minerals. Real gold has a yellow streak, while Fool’s Gold has a black streak.
In addition to the color of the minerals’ streaks, fool’s gold and real gold also differ in hardness. Gold has a low hardness of 2 1/2 to 3 on Moh’s relative hardness scale (roughly the same as a finger nail), while fool’s gold has a hardness of 6 to 6 1/2 (a typical knife blade measures at approximately 5.5). A relative hardness of zero signifies a liquid, while a relative hardness of 10 is equivalent to a diamond.
A mineral’s relative hardness can be tested by scratching. A mineral can only be scratched by a harder mineral, not by a softer one. Therefore, to test the difficulty mineral specimen you can use a distinct mineral with a relative hardness in the middle of that of fool’s gold and that of real gold. For instance, a copper penny with a relative hardness of 3.5 will suffice. Use he difficulty mineral specimen to exertion to scratch the copper penny. If you can scratch the copper penny, then the mineral can not maybe be real gold because it’s softer than copper. The difficulty mineral can therefore be assumed to be fool’s gold (or another mineral with a relative hardness that is higher than that of copper).
In the days of the Gold Rush pyrites and gold were often confused, resulting in much blurring and disappointment. This sometimes leads to the worry in this day and age that fool’s gold and real gold are difficult to distinguish. But fear not, because straight through the above testing methods, fools gold identification is relatively simple.

Where is Gold Found?
gold is familiar and treasured mineral that touches all of our lives, but most of us at some point wonder where gold is found. After all, it doesn’t just appear in ring form wrapped nearby finger or in bullion form locked in a vault somewhere. gold has to be mined before it can be processed and turned into such objects.
The top source of gold in the world over the last 120 years has been The Witwatersrand basin in South africa. Also known as “The Rand”, it has been the source of 40% of the gold found while this time period. A large part of the world’s unmined gold is plan to remain there, with some scientists suggesting the part is up to one third.
After South africa, the second biggest gold producing country is the United states. In singular Nevada, but also other states like Alaska, California, and Colorado have a gold mining output.
After the United States, the third biggest gold producing country is Australia. Gold was first discovered there near Ophir, New South Wales, and today is primarily mined in the Goldfields-Esperance and Pilbara regions of Western Australia, and at Bendigo, Victoria. The largest open-air mine in Australia is the Super-Pit gold mine in Kalgoorie, a town in the Goldfields-Esperance region, and extends 8 quadrilateral kilometers. It is an extraordinary sight to behold.
The above three countries have been the biggest gold producing nations over the last century. But if we part only the current year’s production, China has come to be the world’s largest producer of gold, overtaking South africa‘s top position in 2007. Other countries such as the United States, Canada, and Australia truly have more allembracing gold reserves than China.

Nowadays, thanks to its resistance to corrosion, malleability, infrared reflectivity and thermal conductivity, gold is used in many fields. For instance, it is used in electronics, becoming parts of distinct electronic pieces. Very small gold items may be discovered in computers, movable phones or in larger ones, used by astronauts and doctors. First of all, thanks to its reflective powers, shields which protect spaceships need gold to protect them against solar radiation. Secondly, distinct types of lasers, both commercial and curative use gold-coated reflectors in order to focus on light energy.
In addition, the curative field discovered some other uses for gold. On the one hand, it is one of the most oftentimes used metal in dental industry.

How is Gold Extracted?
gold can be found in any place on Earth in a wide range of concentrations. The small amounts that can be found in the Earth’s crust or in salty water are not adequate to start mental of yourself as being rich.
The foremost fellowships are looking to find areas with big concentrations of gold and are not interested in the stream bed behind your house. gold can be found near the surface of the Earth or in its depth. The gold found in both situations is mixed with other metals such as cooper, silver or lead.
The place where the gold is found dictates the mining process that will be used to extract it. Geologists regularly study the rocks in the region, take samples from the ground and clue the fellowships what needs to be done next.
An discharge site can be secret or it can be an open-pit. An open-pit is used when the gold is settled near the surface of the Earth. Basically it is a huge hole in the ground that has circular roads on the sides. These roads are used for transporting tool in and out of the open-pit. The actual excavation is done with explosives and heavy machines.
Where there is an secret pit means that the gold is found much deeper into the ground. Shafts with tunnels are dug and all roads lead to the load deposit. There is a great deal of financial venture in both types of mining. The cost of the material used (explosives, machines, electric energy for pumping air in the mines etc) can add up to a large number of money.
When the gold has been extracted from the ground the big pieces of gold are made smaller until they reach the consistency of a grain of sand. After this process is over, a cyanide clarification is poured over the grained gold until it becomes a homogeneous mix. The cyanide clarification frees the gold from other metal in it and dissolves it
