Alaska antimony

Alaska, Washington, and Nevada. Ores of the Southeast Missouri lead belt and extensive deposits such as in Silesia and Morocco are of the replacement type. These deposits formed when an aqueous solution of the minerals, under the influence of changing temperature and pressure, deposited the sulfides in susceptible sedimentary rock, usually limestone and dolomites. These ore bodies usually contain galena, sphalerite, and pyrite minerals, but seldom contain gold, silver, copper, antimony, or bismuth. 

World reserves of antimony (5) ate estimated to be from 4—5 million metric tons. Approximately 80% of the world s reserves are located in China, Bohvia, Russia, Thailand, the RepubHc of South Africa, and Mexico China has the world s largest reserves. The United States possesses only 2% of the world s reserves. Most of the antimony produced in the United States is from the complex antimony deposits found in Idaho, Nevada, Alaska, and... 

In 2008, the largest producers of antimony were China, Bolivia, South Africa, Russia, and Tajikistan. The United States produced some antimony concentrate at a mine in Nevada and some antimony metal and oxide in Montana. According to the U.S. Geological Survey (USGS), other states with antimony resources include Alaska and Idaho.
