Extraction of Iron, Iron Mining, Iron Ore Processing

Extraction of Iron, Iron Mining, Iron Ore Processing. As one of the earliest, most widely used metals in the world, iron ore is an important raw material for iron and steel production. At present, iron ore resources are decreasing day by day, which is characterized by more lean ore than rich ore, more associated ore and complex ore composition.

Extraction of scandium from Sc-bearing V-Ti magnetite ...

Abstract: The chlorination roasting and alkali decomposition roasting were used to pre-treat coarse scandium concentrate (Sc 2 O 3 content of 44 g/t) to strengthen the transformation of crystal structure of scandium-bearing minerals and create favorable conditions for further leaching scandium from roasting slag. The results show that scandium leaching efficiency of 84.32% is …
