Ferromolybdenum is smelted from molybdenite or roasted refined molybdenum ore in an electric furnace. The raw material for smelting ferromolybdenum is mainly molybdenite (MoS2). Before smelting, the molybdenum concentrate is usually oxidized and roasted in a multi-hearth furnace to obtain roasted molybdenum ore with a sulfur content of less than 0.07%. Ferromolybdenum smelting generally adopts the outside-furnace method.

The furnace is a cylinder placed on a sand base, lined with clay bricks, and uses ferrosilicon containing 75% silicon and a small amount of aluminum particles as the reducing agent. After the charge is added into the furnace barrel at one time, it is smelted by the upper ignition method. Use initiator on the material surface, and it will react violently after ignition, then calm down, release slag, and dismantle the furnace barrel. The ferromolybdenum ingots are first cooled in the sand nest, then sent to the cooling room to be flushed with water for cooling, and finally crushed and finished. The metal recovery rate is 92 to 99%.

In the steelmaking industry in recent years, molybdenum oxide briquettes have been widely used to replace ferromolybdenum. Ferromolybdenum is usually smelted by metal thermal reduction. First, the molybdenum concentrate (MoS2>75%) is oxidized and roasted to obtain molybdenum calcined sand (MoO3), and then the metal thermal reduction method is used to smelt it to obtain ferromolybdenum.
