Abstract: Self-reducing agglomerates are provided for use in the production of metal. The agglomerates comprise a mixture of iron oxide containing particles and particles of a reducing agent bonded by use of a pre-gel. The agglomerates are produced by a method and apparatus that provides for mixing and curing thereof. The agglomerates may then be used for reduction thereof for the production of iron.

Abstract: A modular apparatus for the production of molten metal by self reduction of agglomerates of metal oxide or of prereduced metal, which may be iron. The apparatus includes a plurality of connected cells of identical size and construction. Each apparatus is connected to equipment for supplying the agglomerates for reduction or melting and refining within a reduction chamber or melting chamber, respectively, of each cell.

Abstract: The present invention refers to a method and an equipment for curing and drying self-reducing agglomerates containing cement as a binder in the presence of saturated vapor at a temperature from about 70 to about 110° C. and under atmospheric pressure. The treatment is performed in one single equipment.

Abstract: A method for reducing metal oxides in a shaft furnace. A charge of metal oxide and a reductant is reacted in the furnace to produce a primary metal of the metal oxide and an additional secondary metal. The temperature of the off gas from the reaction is controlled to prevent condensing of the secondary metal so that it remains in the off gas for separation therefrom.

Abstract: The present invention refers to a method for using electric steel plant slag, ground and/or in particles of less than 6 mm, in self-reducing agglomerates, in the form of pellets or briquettes, as a fluxing material and as a secondary source of iron, in sufficient amounts to adjust the binary basicity of the final slag (ratio of CaO/SiO2) of the reduction/melting process to values equal or greater than 1.1. This application enables a reject that is difficult to discard to be transformed into a secondary source of iron and a final slag having adequate characteristics to be used in the concrete and asphalt paving industries.
