A method for separating non-ferrous metals from ferruginous secondary substances such as residues and slurries from blast furnaces, steel mills, rolling mills, and the like. In accordance with the invention, a layer of the secondary substances is combined in agglomerated form with at least one layer of a sinterable mixture. The non-ferrous metals are volatilized off and recovered in the form of an oxide dust. The recovered dust is separated into at least two fractions having different non-ferrous metal contents and then the dust fractions are sintered with the sinterable mixture.

Method for separating non-ferrous metals from ferruginous secondary

A method for separating non-ferrous metals from an iron-containing waste material which includes providing separate contiguous layers of the waste material and a sintering mixture containing a finely divided carbonaceous fuel, passing hot combustion supporting gases, first through the layer of sintering mixture and then through the layer of waste material in a sintering zone under conditions sufficient to sinter the iron containing constituents, and volatilizing off the non-ferrous metals to produce a charge suitable for feeding to a blast furnace.

Method for separating non-ferrous metals from iron-containing materials

A device for the gasification of carbon containing material to obtain the continuous production of gas, essentially a mixture of carbon monoxide and hydrogen, by using the molten metal bath process is provided. The carbon material, oxidizing agents, and slag-forming additives as needed are introduced into a reactor below the surface of a molten metal bath. The reactor is provided with outlets for the slag, gases, and molten metal. The reactor is also provided with the ability to tilt, swivel, or rotate about a horizontal axis. This rotational movement causes the molten metal bath to alter its location within the reactor, allowing for replacement of the input apparatus of the raw materials, which are normally below the surface, without the necessity of draining the molten metal bath from the reactor.

A casting consisting of a dehydrated agglomerate of particulate material and shaped such that one of its right angle projections is in the form of a trapezoid whose sides include angles greater than 90.degree., the sides being joined by means of curved surfaces.

Casting whose molding takes place during its recovery by means of

An apparatus for producing agglomerates from a rotary filter such as a rotating filter drum, which includes a perforated filter member on the filter, a slotted member disposed on the filter member and a sludge or slurry storage means disposed above the slotted member, the storage means discharging solid particles of the sludge into the slotted member essentially in the direction of solid sedimentation.

Apparatus for the production of molded bodies from filter cakes

Method and apparatus for the production of molded bodies which are shaped by means of a filtration-dehydration process wherein such bodies after shaping are subjected to a rolling movement preferably by means of a roller conveyor to strengthen and homogenize the same before being further processed.
