The antimony ore found in our mine is Stibnite, which is a sulfide bearing ore and is concentrated using a froth flotation process. Typical output is min 20 Sb for roasters, min 25 Sb for blast furnace smelters and min 45 Sb for liquators that melt the antimony sulfide in a reducing atmosphere.
Mined ore deposits occurred as lenses or pockets of stibnite encased in nearly vertical quartz veins. Antimony mining took place intermittently in Arkansas after the metals discovery in 1873. Smelting attempts were made first in 1887 but were unsuccessful. The first commercial production was recorded in

domestic antimony producer in the United States in 2000, Sunshine Mining Company, recovered antimony concentrates as a byproduct of the treatment of complex silver-copper-antimony sulfide ore Carlin, 2000 USGS, 2002. In 2000, imports of antimony ore and concentrate antimony sulfides totaled 3,690 metric tons based on antimony content.
Mineralogically complex antimony deposits are composed of antimony-bearing sulfides and sulfosalts that may contain copper, mercury, lead, gold, or silver. In these deposits, antimony is commonly recovered as a by-product during processing of other ore minerals. Aerial view of the facilities at the former Lake George Mine ca. 1980s.
Food contains small amounts of antimony the average concentration of antimony in meats, vegetables, and seafood is 0.2 to 1.1 parts per billion ppb. 1 People who work in industries that process antimony ore and metal, or make antimony oxide, may be exposed to antimony by breathing dust or by skin contact. 1 Assessing Personal Exposure

The results are presented for using microorganisms for mercury and antimony separation and extraction of oxidized antimony minerals. The problems on technology of direct processing of gold-antimony concentrates by pentachlorous antimony chlorides are considered. The perspective is shown for leaching antimony by alkaline solution of sulfate-reducing bacteria.
By 1938 small-scale operations were occasionally attempted at the mine. An E.B. and Margaret Spitzer of Trona screened ore on the Monarch dump and also attempted some mining on the Kennedy Claim. Their Denver Mine exact location unknown to the writer in Wild Rose Canyon produced a small amount of antimony ore that was treated at the nearby mill.
