Abstract: The present invention relates to a cold-pressed solid agglomerate using an organic binder. In this context, the present invention provides a cold-pressed solid agglomerate containing a mixture which, in turn, comprises at least one main compound and at least one organic binder, wherein the at least one organic binder is obtained by the chemical reaction of starch under controlled pH through at least one alkali in an aqueous medium and at room temperature. Additionally, the present invention provides a process for producing a cold-pressed solid agglomerate, comprising the steps of (i) mixing at least one main compound with at least one organic binder and (ii) cold-pressing the mixture to form an agglomerate, in which the at least one organic binder is obtained by the chemical reaction of starch under controlled pH through at least one alkali in an aqueous medium and at room temperature.

Abstract: Some variations provide a composition for reducing a metal ore, the composition comprising a carbon-metal ore particulate, wherein the carbon-metal ore particulate comprises at least about 0.1 wt% to at most about 50 wt% fixed carbon on a moisture-free and ash-free basis, and wherein the carbon is at least 50% renewable carbon as determined from a measurement of the 14C/12C isotopic ratio. Some variations provide a process for reducing a metal ore, comprising: providing a biomass feedstock; pyrolyzing the feedstock to generate a biogenic reagent comprising carbon and a pyrolysis off-gas comprising hydrogen or carbon monoxide; obtaining a metal ore comprising a metal oxide; combining the carbon with the metal ore, to generate a carbon-metal ore particulate; optionally pelletizing the carbon-metal ore particulate; and utilizing the pyrolysis off-gas to chemically reduce the metal oxide to elemental metal, such as iron. The disclosed technologies are environmentally superior to conventional processes based on coal.

Abstract: To provide a method for recycling processing of dust generated in a converter furnace for collecting the dust at a low cost in a short time and returning it as a metallic iron resource to the converter process. In a method for recycling processing of dust generated in a converter furnace, including: crushing and drying a cake formed by adding a binder to a slurry containing iron powder-containing dust that is generated at the time of converter blowing and wet-collected to produce a mixed slurry and subjecting the produced mixed slurry to a dehydration treatment in a filter press; accumulating the cake in an accumulation tank; and charging the cake into a converter furnace 10, the crushed product in the accumulation tank 25 is kept at a temperature of less than 90°C by forcibly passing air into the accumulation tank 25 and charged into a converter furnace according to the converter operation.

Abstract: The method of recycling of secondary slag in the primary smelting of iron: the secondary slag is treated by following steps - natural cooling, de-metallization, mechanical processing and sorting, compaction of its part into a compact form, while secondary slag with metallurgical additives is added as an additive into the primary melting within the mixture with added lime in the weight ratio of 1: 0.5 - 10, wherein the under-sieve slag of 0-12 mm fraction is compacted into the compact form by vibration pressing with addition of 2-35 % by weight of the binder, and then it is dried for 5 hours to 1-7 days under standard atmospheric conditions, depending on used binder; the binder is Portland cement, molasses, lime, lime milk, magnesium cement, bentonite, or their combinations, or it is compacted into the compact form by pressing under high pressure so that the interrelationship of the particles occurs by Van der Waals forces, and the over-sieve slag of 12-50 mm fraction is used in original condition without previous treatment.
