Technology to find gold (File )
Not only is gold confined to ornaments, but it is also a key indicator of economic prosperity of any nation. It is for this reason that nearly all nations of the world are always on the lookout for expanding their gold reserves. Various nations are looking for new gold mines so as to enhance their resources.
In such a scenario, people wonder in their minds that how do scientists locate gold hidden below the earth's surface? Do they have any machine that would inform them of how much gold is hidden at what depth level? Scientists adopt cutting-edge techniques to solve this mystery. Let us learn about how to identify the hidden treasure within the earth. Ground
The first method employed by geologists is Ground Penetrating Radar i.e. GPR. Through this method, various layers of soil are examined. Signals emitted by the GPR when they strike the layers underneath the ground show if there is any metal there or not. Researchers examine these signals thoroughly and hypothesize whether the metal discovered is gold or not. Only when they are sure that the metal beneath is gold, the excavation process is continued.
The second significant technology is VLF i.e. Very Low Frequency Technology. In this, geologists employ electromagnetic waves, which are transmitted within the ground. When these waves reflect after striking a metal, their speed, sound and direction identify
Gold behaves differently from other metals so it is easy to estimate if the element beneath the earth is gold or another metal. This method operates very closely and provides scientists with more precise information.
Once the fact has been established that gold is deposited underground, excavation begins. Complex engineering procedures are taken for this purpose. The rocks are drilled using drilling machinery and blasting is also performed as required.
Most people have an illusion that tons of gold is available in the mine, but the reality is just the opposite. There is only a handful of grams of gold from a huge stone and that too after passing through many intricate processes. Gold exists as gold ore in most cases, which gets converted into pure gold after processing.
