A number of US scientists working to find a way to pan for gold and other precious metals contained in human feces. The exposure of these efforts put forward a group of the US Geological Survey (USGS) researchers at the 249th national meeting of American Chemical Society (ACS) in Denver, Colorado.

According to Dr. Kathleen Smith, as one of the leaders of the research team, precious metals in sewage treatment centers and dirt so the potential for fed though a bit. "The content of gold which we found at a minimal level," said Smith.

In addition to gold and silver, the team found other rare metals in human feces, such as palladium and vanadium. Scientists experimenting with using a chemical called leachate. The substances commonly used in mining projects to gain metal from rock layers.

Although leachate had a bad reputation for being able to damage the ecosystem when leaked or spilled into the environment, Smith said, the substance was safe to wash the metal of solid waste in a manner that can be controlled and monitored.

"We are interested in getting precious metals that can be sold, including vanadium and copper. The metals that are used in mobile phones and computers," said Smith.

Smith and her colleagues predict that the seven tons of solid waste processing in the US. waste processing facilities every year. About half of that amount is used as agricultural fertilizer and forest. The other half is burned or sent to landfill.

If the study of Smith and his colleagues was a success, no longer solid waste disposed of in vain. Moreover, in a previous study, a group of other scientists calculate that the sewage from one million Americans most likely to contain metals worth U.S. $13 million.

If the attempt is successful, will you store the your feces as an investment in the future? *** [EKA | FROM VARIOUS SOURCES | BBC]
