“…galvanized scrap enables several ways of processing these kinds of by-products. 6) Recycling of these materials in existing iron-and steelmaking processes without pre-treatment is difficult due to the adverse impact on the process operation and the product quality which might be caused by the impurities, fine particle size, high moisture content, etc. 7) Attention has been paid by several researchers to investigate different routes of effective utilization of these materials as well as their impact on process performance.…”

“…No entanto, a presença de zinco, ainda que pequena, impossibilita a reutilização direta do resíduo, pois esse elemento, quando carregado no alto-forno, acarreta na formação de uma crosta na parede do reator. Portanto, para recuperar o ferro é necessário remover o zinco (Brehm et al, 2006;Dutra et al, 2006;Silva et al, 2008;Trung et al, 2011).…”

“…No entanto, ao contrário do ZnO que é uma espécie facilmente removível em meio aquoso ácido e/ou básico, o ZnFe 2 O 4 se apresenta de difícil remoção devido à elevada estabilidade química (Silva et al, 2002;Havlik et al, 2005;Dutra et al, 2006;Trung et al, 2011). Sendo assim, apesar dos bons resultados obtidos pelos pesquisadores, a solubilidade das ferritas de zinco (franklinita) tanto em meio ácido quanto em meio alcalino ainda é muito baixa.…”

“…This waste is inefficiently redesigned, causing considerable economic and environmental losses. With the development of novel science, technology, and environmental protection, the trend of improving production technologies and minimizing waste production and waste storage in landfills is increasing [3].…”
