Abstract: A direct smelting plant for producing molten metal from metalliferous feed material includes a pretreatment unit for pretreating metalliferous feed material and producing pretreated feed material, a direct smelting vessel for smelting pretreated metalliferous feed material to molten metal and a hot feed material transfer apparatus for transferring pretreated metalliferous feed material from the pretreatment unit to a solids delivery device of the direct smelting vessel. The transfer apparatus includes a hot feed material storage device, a hot feed material transfer line, device for unblocking the hot feed material transfer line and a pressurising device. The hot feed material transfer apparatus includes a device for returning pretreated metalliferous feed material to the pretreatment unit.
