【 摘 要 】

This research was developed by considering that the solid waste producedin the process of pig iron production represents the loss of raw materials andthe increase in environmental problem. The charcoal based mini blast-furnaceoff gases dust named CHARCOK was collected from SIDERPA ¾ Siderúrgica Paulino Ltda, located in Sete Lagoas, MinasGerais. The Charcok was characterized and classified according to ABNT (AssociaçãoBrasileira de Normas Técnicas) standard. The results showed that theCharcok 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 asenergy source.
