But traditional extraction releases enormous amounts of toxic mercury and cyanide, especially from small-scale mining, which emits over 2,000 tons of mercury every year, according to the United ...

A Cornell-led research team has developed a method for extracting gold from electronics waste, then using the recovered precious metal as a catalyst for converting carbon dioxide (CO2), a ...

Many techniques have previously been reported for extracting gold from ore or e-waste, including mercury- and cyanide-free methods.

A Cornell University-led research team has developed a method for extracting gold from electronics waste, then using the recovered precious metal as a catalyst for converting carbon dioxide (CO2 ...

And increasingly valuable. In a new study, researchers from ETH Zurich, Switzerland, have detailed a sustainable, cost-effective method of selectively extracting gold from electronic waste or e-waste.

Chemistry postgraduate student Zhichang Liu has discovered -- by accident -- a new method of extracting gold, using (of all things) corn starch instead of cyanide ...

In an article published in Nature, the research team detailed a new method for extracting gold from existing e-waste (via Techxplore).

London - The U.K.'s Royal Mint, the country's official coinmaker, has opened a factory that will extract gold from e-waste to reduce its reliance on traditional mining and encourage more ...
