description This work corresponds to a study on pellet reduction formed from mixtures of iron ore from Topaipí (Department of Cundinamarca, Colombia) with two iron ores coming from Cerro San Isidro and Cerro Altamira (State of Bolivar, Venezuela). This ferrous mineral benefaction technique has been used for several decades in the steel industry in order to recover fine materials, generated in the processes previous to their use; which in actuality mixtures are made between low grade and high grade metal are created. These iron ore metals, mixtures, and the components to be added to make the pellets were categorized by their chemical, physical, and mineralogical components through X-ray diffraction and chemical analysis. After drying, the pellets were reduced in the laboratory in a Linder furnace at 850 and 1000°C during 160 minutes. The purpose was to evaluate the degree of metallization and basicity indices of the direct reduced iron (DRI). This was done in order to partially substitute the scraps in the electric arc furnace and consequently, make ferrous products. The analysis showed that the mixtures increase the iron content and better the basicity indices. A metallization degree of 81.20 and 95.1% were obtained. This demonstrates that the ratio of mineral used in the mixture, taking into account the chemical composition of the minerals and the contents added in the production of the mixture, is appropriate and the DRI obtained meet the expected specifications.

Esta técnica de beneficio de minerales ferrosos se aplica hace varias décadas en la industria siderúrgica para recuperar los materiales finos generados en los procesos previos a su utilización; en la actualidad se realizan mezclas entre minerales de baja ley con otros de alta ley. Se caracterizaron química, física y mineralógicamente los minerales de hierro, las mezclas y los compuestos de adición para elaborar los pellets, para lo cual se empleó difracción de rayos X y análisis químico. Después de secados, los pellets fueron sometidos a reducción en el laboratorio, en un horno tipo Linder, a 850 y 1000°C, durante 160 minutos. El propósito fue evaluar el grado de metalización y los índices de basicidad de los prerreducidos, para sustituir parcialmente la chatarra en el horno eléctrico de arco y la consecuente elaboración de productos ferrosos. Los análisis revelan que las mezclas consideradas incrementan el contenido de hierro y mejoran los índices de basicidad, pues se obtiene un grado de metalización con valores entre 81,20 y 95,1%. Esto permite concluir que la relación de mineral empleada en las mezclas es apropiada y los prerreducidos obtenidos cumplen con las especificaciones esperadas.O presente trabalho tem por objetivo o estudo da redução de péletes formados a partir de misturas de um mineral de ferro proveniente de Topaipí (Departamente de Cundinamarca, estado da Colômbia) com dois minerais de ferro provenientes da Serra de San Isidro e Serra de Altamira (Bolivar, estado da Venezuela). A técnica de benefício dos minerais ferrosos é aplicada há várias décadas na indústria siderúrgica para recuperar materiais finos, gerados nos processos prévios a sua utilização; na atualidade são feitas misturas entre minerais de baixo teor com outros de alto teor são feitas. Os minerais de ferro, as misturas e os compostos de adição para a fabricação de péletes foram caracterizados química, física e mineralogicamente, utilizando a técnica de análise por difração de raios X e a análise química. Os pellets depois de ser secados, foram submetidos a redução no laborátorio, num forno tipo Linder, a 850 e 1000 °C durante 160 minutos. O objetivo foi avaliar o grau de metalização e o índice de basicidade, obtendo-se um grau de metalização entre 81,20 e 95.1 %. O resultado permite concluir que a relação de mineral empregada nas misturas, a composição química dos minerais e os conteúdos de adições utilizadas para a elaboração das misturas, é apropriada e os pré-reduzidos obtidos cumprem as especificações esperadas.application/pdfspaUniversidad Santo Tomás Seccional Tunjahttp://revistas.ustatunja.edu.co/index.php/ingeniomagno/article/view/1166/1130Ingenio Magno; Vol. 7 (2016): Ingenio Magno Vol. 7-1; 46-612422-23992145-9282Copyright (c) 2016 Ingenio Magnohttp://purl.org/coar/access_right/c_abf2Determinación del grado de metalización de pellets de mezclas de minerales de hierro reducidos en horno LinderDetermination of degree of metallization of pellets from an iron mixture, reduced in a Linder furnaceDeterminação do grau de metalização de péletes misturas de minero de ferro reduzidos em um forno Linderinfo:eu-repo/semantics/articlehttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_2df8fbb1BasicityMetallizationPelletsReductionDirect reduced iron (DRI)BasicidadMetalizaciónPelletsReducciónPrerreducidosBasicidadeMetalização de péletesReduçãoPré-reduzidos11634/4991oai:repository.usta.edu.co:11634/49912023-07-14 16:33:48.069metadata only accessRepositorio Universidad Santo Tomásnoreply@usta.edu.co
