Dec 22, 2016· The former product is re-treated in the antimony softening furnace, being slowly worked off with the current softened bullion, while the latter is treated in a small blast furnace producing antimonial lead and waste slag. As indicated above, the normal cycle of softening a charge is 12 hours.
Dec 04, 2000· The blast furnace is generally used for mixed sulfide and oxide ores. Antimony is often found associated with lead ores. The smelting and refining of these ores yield antimony‐bearing materials that may be treated to recover elemental antimony. Recycling of antimony provides a large proportion of the domestic supply of antimony.
In 1965, the United States Steel Corp. was the largest steel producer in the world. In the U.S. it still operated 16 blast furnace sites. One of their lesser known plants was Central Furnaces in Cleveland, OH. This plant was founded in 1881 by the Cleveland Rolling Mill Co. and supplied iron to the Newburgh steel mill until it was closed in 1933.
