Resumo

O presente trabalho avaliou a reutilização de finos de minério rejeitados do peneiramento na alimentação do alto-forno de uma empresa siderúrgica, através do processo de pelotização, com prévia etapa de concentração gravítica. Para a etapa de pelotização, objetivou-se a produção de 03 tipos de pelotas. Duas das preparações utilizaram pellet feed beneficiado de uma pelotizadora e finos de minério, com e sem concentração prévia. Por último, uma preparação de pelota foi produzida apenas com os finos de minério após concentração. Na etapa de caracterização das pelotas, o produto obtido da mistura do pellet feed beneficiado, insumos da pelotizadora e dos finos concentrados, foi o que apresentou melhor resultado no teste de resiliência e maior teor de ferro (63,5%) após a queima. Entretanto, a pelota produzida utilizando apenas o concentrado de finos de minério apresentou melhor resultado no teste de resistência à compressão. Desta forma, avaliando apenas aspectos químicos e mecânicos, a utilização dos finos de minério da siderúrgica para a produção de pelotas demonstrou ser tecnicamente viável.

 

The present work evaluated the reuse of iron ore fines from sieving in the blast furnace of a pig iron producer, through the pelletizing process, with a previous stage of gravitic concentration. For the pelletizing stage, the objective was to produce 03 types of pellets. Two of the preparations used pellet feed benefited from a pelletizing plant and iron ore fines, with and without previous concentration. Finally, a pellet preparation was produced only with the ore fines after concentration. In the pellet characterization stage, the product obtained from the mixture of the benefited pellet feed, pelletizing additives and the concentrated fines, presented the best results in the resilience test and higher iron content (63.5%) after burning. However, the pellet produced using only the ore fines concentrate showed the best result in the compressive strength test. Thus, by evaluating only chemical / mechanical aspects, the use of iron ore fines for the production of pellets proved to be technically feasible

Whoops, looks like something went wrong.
