The state-of-the-art technology in the production and application of ferroalloys containing rare earth and alkaline earth metals is considered. The possibility of developing wasteless production of such ferroalloys using ore-coal briquettes is demonstrated. It is shown that for out-of-furnace processing of steel, multicomponent alloys with a microcrystalline structure are most efficient.
