【 摘 要 】
This research was developed by considering that the solid waste produced in the process of pig iron production represents the loss of raw materials and the increase in environmental problem. The charcoal based mini blast-furnace off gases dust named CHARCOK was collected from SIDERPA ¾ Siderúrgica Paulino Ltda, located in Sete Lagoas, Minas Gerais. The Charcok was characterized and classified according to ABNT (Associação Brasileira de Normas Técnicas) standard. The results showed that the Charcok should be classified as Class I Wastes ¾ "Hazard Wastes" because of its high concentration of phenols (54.5mg C6H5OH/kg). The Charcok had high concentration of iron and charcoal which can be used as energy source.
