Abstract: Disclosed is a direct smelting plant and a direct smelting process for producing molten metal from a metalliferous feed material, such as ores, partly reduced ores, and metal-containing waste streams. The direct smelting process includes the steps of pretreating metalliferous feed material in a pretreatment unit (3) and producing pretreated feed material having a temperature of at least 200°C; storing pretreated metalliferous feed material having a temperature of at least 200°C under pressure in a hot feed material storage means (61); transferring pretreated metalliferous feed material having a temperature of at least 200°C under pressure in a hot feed material transfer line (11) to a solids delivery means of a direct smelting vessel (5), and; delivering pretreated metalliferous feed material into the direct smelting vessel and smelting metalliferous feed material to molten metal in the vessel.

Abstract: In accordance with the invention, refining raw materials containing organic constituents, such as solids containing oil and/or bitumen, in particular oil or tar sand or oil shale, is effected with the following steps: - supplying the raw materials to a reactor and expelling fuel gases at a temperature of about 300 to 1000°C, preferably about 500 to 800°C, introducing the solids left in the reactor including the non-evaporated fractions of heavy hydrocarbons into a furnace, burning the heavy hydrocarbons left in the solids in the furnace at a temperature of 600 to 1500°C, preferably 700 to 900°C, recirculating hot solids from the furnace into the reactor, wherein the oxidizing atmosphere of the furnace is separated from the atmosphere of the reactor by means of a blocking device.

Abstract: A direct reduction process for a metalliferous material includes supplying a solid carbonaceous material and an oxygen-containing gas into a fluidized bed in a first vessel and generating heat by reactions between the oxygen-containing gas and the solid carbonaceous material and any other oxidizable solids and gases in the fluidized bed and discharging a hot off-gas stream containing entrained solids. The process also includes supplying the metalliferous material to a fluidized bed in a second vessel and supplying the hot off-gas stream containing entrained solids from the first vessel to the fluidized bed in the second vessel and partially reducing the metalliferous feed material in the solid state in the fluidized bed and discharging a product stream of partially reduced metalliferous material and an off-gas stream containing entrained solids.
