摘要： A process and system for producing metalized iron agglomerates and for recovery of zinc values from waste materials, in dust form, including comminuting and drying the dust. Collecting and separating the dust in accordance with the content of the zinc values and proportionately blending the dust to provide a product having a substantially uniform zinc value content for pelletizing into green balls. Drying and indurating the green balls and reducing the indurated balls with a reductant to provide highly metalized balls and volatilization of the zinc values. Recovering the volatilized zinc values, as exhaust gases, to provide metalized balls having a high iron content substantially free of zinc values.

摘要： A method of recovering iron and oxide impurities from steel furnace dust in which the dust first is mixed with finely divided coke and then this mixture is pelletized. The green pellets thus formed are deposited over a layer of burnt pellets on a rotary hearth which successively conveys the pellets first through a drying zone, then through an initial heating zone in which the pellets are gradually raised to a temperature at which the coke starts to burn, then through a decontamination zone in which the pellet temperature is rapidly raised to a degree at which zinc, lead and sulfur impurities vaporize and in which these impurities are carried off and collected as oxides, and finally the pellets are carried through a reoxidation and hardening zone in which the temperature thereof is further increased to a sufficient degree and held for a long enough period of time to permit the growth of grains of an oxide of iron on the surface of the pellets, thus to form hard bonded pellets which are not fused together.

摘要： Particulate scrap iron is disposed of by blending it with a bituminous, hydrocarbonaceous binder, forming briquettes from the mixture, and treating the briquettes with an oxygen-containing gas at 350* to 600*F to selectively react with the hydrogen and unsaturated hydrocarbon in the binder, to obtain strong briquettes which can be used as a source of iron in steelmaking processes.

摘要： HIGHLY FLUXED IRON OXIDE PELLETS ARE MADE FROM IN-PLANT WASTE PRODUCTS AND FLUXSTONE. A MIX SUITABLE FOR BALLING IS FORMED. THE MIX CONTAINS NOT MORE THAN ABOUT 35% OF IN-PLANT WASTE PRODUCTS WHICH CONTAIN METALLIC IRON AND FERROUS IRON, NOT LESS THAN ABOUT 35% IN-PLANT WASTE PRODUCTS WHICH CONTAIN IRON OXIDES, AND NOT MORE THAN 30% FLUXSTONE, FOR EXAMPLE DOLOMITE. THE CARBON IN THE MIX IS NOT MORE THAN ABOUT 0.5%. SULLICIENT WATER IS ADDED TO INSURE PROPER BALLING. THE MIX IS BALLED. THE GREEN BALLS ARE DRIED AT A TEMPERATURE IN THE RANGE OF ABOUT 212* F. TO ABOUT 600*F. THE DRIED BALLS ARE HEATED TO WITHIN A TEMPERATURE RANGE OF ABOUT 1000*F. TO ABOUT 1200*F. WHEREIN A SUBSTANTIAL PORTION OF THE CARBON IS BURNED OFF AND THE OXIDATION OF METALLIC IRON AND FERROUS IRON TO A HIGHER IRON STATE OCCURS. THE TEMPERATURE OF THE DRIED BALLS IS RAISED TO A RANGE OF ABOUT 2150*F. TO ABOUT 2350*F. WHEREIN THE BALLS ARE HARDENED TO FORM PELLETS. SUBSTANTIALLY ALL OF THE METALLIC IRON AND FERROUS IRON ARE OXIDIZED TO THE HIGHER VALENCE STATES.

摘要： IRON OR IRON OXIDE FINES SUCH AS BOF DUST, IRON ORE, AND MILL SCALE ARE FORMED INTO STRONG CERAMIC BONDED COMPACTS SUITABLE AS RAW MATERIAL FEED FOR STEEL MAKING OPERATIONS, E.G. BLAST FURNACE FEED. A NOVEL COMBINATION OF ADDITIVES, AMMONIUM HYDROXIDE, A MINERAL ACID SUCH AS HYDROCHLORIC ACID, A CARBOHYDRATE BINDER SUCH AS MOLASSES, AND WATER, PROVIDE THE NECESSARY LOW TEMPERATURE

STRENGTH UNTIL A CERAMIC BOND IS ESTABLISHED. THE COMPACTS ARE FORMED FROM THE COHESIVE MASS, PREFERABLY BY EXTRUSION, DRIED AND FIRED IN A CONVENTIONAL MANNER.
