• Description:
  "The U.S. Bureau of Mines investigated recovery of manganese from basic oxygen furnace (bof) steelmaking slags because the slags represent a large potential resource of a metal for which there is no domestic production. Bof slags were leached using fluosilicic acid, a byproduct of the fertilizer industry. Manganese and iron were extracted as soluble manganous and ferrous fluosilicates, while the calcium and magnesium remained in the tailings as insoluble fluorides. Treating the pregnant liquor with sodium chloride precipitated sodium fluosilicate (na2sif6), which was recovered as a byproduct. Manganese and iron were precipitated as hydroxide- carbonate salts with the addition of sodium carbonate to the treated liquor. Recoveries for manganese and iron were 73 to 83 and 67 to 70 pct, respectively." - NIOSHTIC-2
