    Abstract: A device and a method for removing oil from lubricating oil−adhered fine scales produced in an iron manufacturing process and metal working process and oil−adhered metal particles produced in a metal working process for economically recycling oil−adhered particulates by performing a deoiling treatment, wherein the oil−adhered particulates and oil−adhered metal powder are mixed with water to form slurry, the slurry is sent to a centrifugal separator, the slurry is treated there by a centrifugal force of 300 times a gravity or more to separate the water and oil from the particulates and metal powder by properly setting the volume ratio of the slurry particles to the water and the relation between the centrifugal force and the particle residence time in the centrifugal separator.

    Abstract: A mixture comprising a metal oxide-containing powder and a carbon powder and water in an amount of 100 % or more relative to the total mass of both the powders is agitated for mixing to form a slurry. The slurry is dewatered so as to have a water content of 16 to 26 %, and the resultant product is subjected to compression molding to produce cylindrical or granular moldings having a thickness or diameter of 30 mm or less. The moldings are charged into a portion having an atmospheric temperature of 1170 DEG C of a reducing furnace of rotary hearth type, and thereafter is reduced in the furnace to produce a metal. The above method for operating a reducing furnace of rotary hearth type allows the simplification of the process from dewatering to molding and thus results in a process for reducing a metal oxide at a lower cost, and further can provide a method for economical recycling of the dust and sludge produced in a process of refining or working of a metal.
