Making Gold Green New NonToxic Method for Mining Gold

May 14 2013 By Megan Fellman. EVANSTON Ill. Northwestern University scientists have struck gold in the laboratory. They have discovered an inexpensive and environmentally benign method that uses simple cornstarch instead of cyanide to isolate gold from raw materials in a selective manner. This green method extracts gold from crude sources and leaves behind other metals that are often found mixed together with the crude gold.
