Aluminothermic process for the preparation of Ferromolybdenum and Ferrovanadium

The paper presents laboratory development of processes involving aluminothermic reduction, in open reactors, for the preparation of ferromolybdenum and ferrovanadium starting from indigenously available resources. The coverage incorporates chemical processing that has been
developed for treating the starting resources such as low grade sulphide concentrate/molybdenum scrap/molybdenum laden solution for molybdenum and vanadium bearing slag or vanadium sludge for vanadium to prepare suitable intermed-iates. These essentially constitute raw materials develop-ed as alternative to the conventional ores for the two ferroalloys.
