Breakthrough clean gold mining technique replaces cyanide ...

May 21, 2013· This accidental discovery will hopefully transform the industry. After more tests, it was discovered that alphacyclodextrin, a cyclic starch fragment composed of six glucose units, was best at isolating gold from the solution. But not only is this process a lot less toxic than the cyanide leaching process, it also appears to be more efficient at isolating gold.
