Gold and Tailings: The Standard Mill at Bodie, California

The bullion produced from the concentrates was fairly base (because of the iron content) and largely silver (only about 100 fine gold and 650-850 fine silver) Tailings went to the ponds, where water drained from the solids until they were thick enough to be excavated and re-treated in the cyanide plant[37] The New Standard Mill.
