Iron ore isn't pure iron oxide – it also contains an assortment of rocky material. This wouldn't melt at the temperature of the furnace, and would eventually clog it up. The limestone is added to convert this into slag which melts and runs to the bottom. The heat of the furnace decomposes the limestone to give calcium oxide.

The lime roasting method is the earliest method used to extract lithium from spodumene [27]. Spodumene is mixed with lime or limestone for roasting. Sufficient amount of CaO destroys the mineral structure at high temperatures over 1100°C [28–29]. The roasting reaction is shown in reaction (1). The calcine is leached to obtain the LiOH solution.
