the Yellow Pine and Meadow Creek mines of the Bradley Mining Co. The Yellow Pine mine was the largest source of tungsten and antimony ores in the United States from 1942 to 1944. Gold and silver ores also are taken from this mine. Only gold, antimony, and silver ores were mined in the Meadow Creek mine, which was closed in 1938. Quartz ...

Jan 01, 2011· The temperature and relative concentrations of Na 2 S and NaOH in the leach were identified as the most important factors affecting the extraction of antimony and the subsequent cyanide extraction of silver and gold. The highest gold and silver extractions were 78% and 91%, respectively, corresponding to an increase of 29% and 74% compared to ...

Jan 01, 2016· The association of gold and antimony in many ores provides additional complications in the gold extraction process. Improvements in mineralogical identification and understanding of the chemistry of the cyanidation process with antimony present are leading to improved treatment processes for antimonial gold ores.

Abstract This study investigated the leaching and electrowinning of antimony from a complex, high arsenic and gold-containing stibnite concentrate ore (As-Au-Sb ore) using slurry electrolysis (SE). The results indicated that the leaching efficiency of antimony was higher than 98%, and those of iron and arsenic were about 5.50% and 1.14%, respectively.

"Antimony is often a high-level indicator of deeper gold deposits," said Barker. Later investigations by Bear Creek Mining included samples topping 1 oz/t gold, as well as antimony-rich samples with gold, silver and arsenic. Hed and Strand, a mine in the Lost River area about 85 miles northwest of Nome, also produced antimony during World War I.
