American geologists have proposed to start mining precious metals in a most unexpected place. Obtaining, for example, gold from sewers, as experts are sure, will add to the American treasury millions of dollars and also help the environment.
Scientists report that the human body along with excreted excretes many substances, including such metals, like platinum, gold and silver. Of course, one person lowers into sewer extremely few of these precious metals, however, underground flowing whole seas of feces that can be considered as a promising alternative to gold mining.
Such a practice will bring many-sided benefits. Besides to produce precious metals, America will be able to clean thousands of tons sewer water and use it for various purposes, for example, field irrigation in arid regions.
It is reported that every year any American city with a population over a million people throw precious metals for at least thirteen million dollars. Wherein extracting so much gold, silver and platinum will cost less than half a million. Net profit is easy to calculate.
Although the mission of splitting sewer products for receiving gold does not look very nice, in fact the prospects of such an undertaking can hardly be overestimated. Precious metals, by the way, are contained not only in our excrement, but also in soap, shampoos, food – in a word in almost everything that we used to run into stock.
