Since humanity has mastered the extraction of minerals, technological progress developed at a rapid pace. Development of mineral resources is the basis of well-being of many countries, although, of course, these resources are not infinite, and people should already think about alternative energy sources. However, work is being done in this direction as well, although the dependence on minerals is still very high and will undoubtedly remain so for a long time.
Facts about minerals
- All are divided into three main types - liquid, gaseous and solid.
- The first place in terms of extraction of all minerals is hard coal. The energy industry of many developing countries still depends on it.
- The first surgical instruments in the world were made of obsidian, or volcanic glass. This mineral is formed when magma erupts to the surface, under the influence of extreme temperatures.
- Sometimes mining harms nature. For example, the most toxic lake in the world, in the United States, was formed when water flooded a former copper mine.
- The first theory of what oil was was that it was whale urine. At that time, oil was extracted by simply collecting it from the surface of bodies of water.
- The most flexible metal extracted from the Earth’s bowels is gold. One ounce of it is enough to produce a string almost 80 kilometers long.
- The most important minerals for the development of humanity were metals and fuel. It was the mastering of the mining and processing of hard coal and iron that pushed technological progress dramatically forward.
- Platinum, which is now worth a lot of money, was first discovered by Europeans in the 16th century, in the New World. And at first it was valued very low, considering that even silver is worth more. And now platinum is one of the most expensive minerals.
- Often, several types of minerals can be found together. For example, natural gas is often dissolved in oil.
- One of the most resistant minerals used for construction since ancient times is granite. It can withstand the effects of wind and moisture for centuries without losing its original appearance.
- The hardest mineral extracted from the Earth’s interior is the diamond.
- Uranium has 14 stages that it goes through over time, all the while generating dangerous radiation. Eventually it turns into ordinary lead, but this process takes about 1 billion years.
- The only metal that cannot spark when it strikes one piece against another is copper.
- Sometimes human error leads to the senseless waste of valuable minerals. A striking example is the Darvaza crater in Turkmenistan, which has been burning for decades. The Soviet specialists set fire to the gas coming out of it, thinking that it would burn out quickly and not interfere with further exploitation, but the flame is still blazing.
- Such a mineral as peat is an excellent preservative. Sometimes in peat bogs are found perfectly preserved bodies of people and animals that got there hundreds of years ago.
- Only about 6% of all the salt extracted food. The rest goes to industry.
