| Abstract: | Ludwigite ores contain Fe,B 2O 3 and MgO.Iron and boron were separated by magnetic separation and blast furnace smelting according to the characteristics of the low grade ludwigite ores.The pig iron containing boron and boron rich slag(B 2O 3 12%) are obtained.The boron rich slag was leached by sulfric acid to produce boric acid and pregnant liquor that contains H 3BO 3 and MgSO 4.The kieserite was produced by means of high temperature crystallization from the pregnant liquor.The comprehensive utilization of Fe,B and Mg contained in ludwigite ores was achieved. |
