American scientists have proposed an innovative way of production of non-ferrous metals, in particular - gold. The fact that the trash is used to extract useful elements has long been known, but that the same extract useful elements from sewer water can - became known only now.

The scientific team from the University of Arizona studied wastewater in 94 US cities. A series of tests have found that the water every city there is a set of 50 different metals, among them such as platinum and gold. It is noteworthy that 50 of metals contained in the water each city, but in addition there were dozens more impurities depending on the local economic context.

Preliminary calculations show that if the extract gold from impurities, it can bring the US $ 13 million for every 1 million people in the country. Needless to today technology that would allow efficient extraction of gold from the slop water - no. However, this news is so inspired researchers at the University of Arizona, they opened a special branch is engaged in the study of this issue.

In fact, the value of the opening is not possible in mining precious metals. Removing all impurities from the water could improve the environment. The fact that the standard procedure for cleaning water reservoirs in urban piped water does not get rid of the metals.

As for the potential economic benefits, the removal of metal contaminants from the water could really help get a large amount of non-ferrous metals. Among the most valuable, even scientists have found in the water of some elements of rare earth metals, widely used in electronics. Removing them from the water, you can already today, but unfortunately, all the known methods of science and industry today is not economically profitable.
