Abstract

"PROCESSO DE AGLOMERAçãO DE REJEITOS E SUBPRODUTOS SIDERúRGICOS ATRAVéS DO USO DE LIGANTES COMBINADOS". Concernente à área de aglomeração de rejeitos e subprodutos siderúrgicos e baseado na aglomeração química destes materiais visando à produção de aglomerados em forma de briquetes, pastilhas, produtos extrudados e pelotas para posterior utilização em processos de produção industrial que requeiram um controle estreito das características físicas, metalúrgicas e químicas dos materiais a serem empregados: faixa granulométrica adequada, composição química uniforme e adequadas características físicas para manuseio, transportes e enfornamento tal como ocorre na produção de gusa em altos fornos. O processo consiste na utilização de ligantes químicos tais como: borato alcalino, hidróxidos, silicatos e metassilicatos alcalinos com o uso de compostos auxiliares de endurecimento tais como diatomita, dióxido de silício precipitado, sílica ativa, finos do coletor de produção de ferro sílico manganês, hidróxido de cálcio e calcário."Process for Agglomeration of Tailings and Steel Substances through the Use of Combined Binders". Concerning the area of tailings and by-products agglomeration and based on the chemical agglomeration of these materials aiming at the production of agglomerates in the form of briquettes, pellets, extruded products and pellets for later use in industrial production processes that require close control of physical characteristics, metallurgical and chemical properties of the materials to be employed: adequate particle size range, uniform chemical composition and adequate physical characteristics for handling, transport and hanging as in the production of pig iron in blast furnaces. The process consists of the use of chemical binders such as: alkaline borate, hydroxides, silicates and alkaline metasilicates with the use of hardening auxiliary compounds such as diatomite, precipitated silicon dioxide, active silica, manganese silica iron collector fines, calcium and limestone hydroxide.
