    Although cyanide is cheap, effective, and biodegradable, its high toxicity has led to new methods for extracting gold using less toxic reagents. Other extractants have been examined including thiosulfate (S 2 O 3 2−), thiourea (SC(NH 2) 2), iodine/iodide, ammonia, liquid mercury and alpha-cyclodextrin....

    Leaching for gold: Some say cyanide leaching mining is

    While cyanide in mining is nothing new, using heap leaching to process gold didn't come along until the 1970s, McCullough said, when the first such mine was opened in Nevada. The process opened up the door to mining ore previously considered marginal because it allows miners to extract tiny pieces of gold widely diffused through much larger, lower-grade ore bodies....

    'Green' gold extraction method replaces cyanide with

    The most common method is cyanide leaching, where cyanide salts in solution are used to suck the gold out from its ore. You get gold, but you also get highly toxic byproducts. However, chemistry postgraduate student Zhichang Liu has discovered -by accident -a new method of extracting gold, using (of all things) corn starch instead of cyanide....
