Gold and Tailings: The Standard Mill at Bodie, California

A month after Standard’s cyanide plant started re-treating tailings, Merrill’s analysis showed that costs of operation were less than $1.25/ton to extract gold and silver worth about $4.00/ton. By December 1894, Standard’s new cyanide plant had recovered $16,000 worth of gold and silver, an important contribution to the company’s total

nature. Where amalgamation plants could recover about 60% of the gold present, cyanide could recover about 90%. Because of the improved recovery, many of the old tailings piles from other processes have been economically reprocessed by cyanide leaching. Cyanide is as close to a “universal solvent” for gold as has been developed.
