Brazil has a diversity of mineral resources. In this unit, we learned the importance of the production of hematite, limestone and bauxite in Brazilian industry. Brazil has mines of great global importance in the production of bauxite, such as the mines of Alcoa S. A. As for iron mines, Vale is the largest Brazilian producer of iron ore. Regarding limestone production, at least 22 Brazilian states have limestone mines. Many statements are made below about the aspects that hematite, bauxite and limestone mines have in common. Is the only correct alternative? Alternatives: The) The production of aluminum from alumina does not even require a flux. B) The three types of mines, hematite, bauxite and limestone, cause environmental impacts. w) Mineral coal is irrelevant for the production of iron from hematite. d) Limestone mines do not impact the water cycle. It is) The electrolysis of alumina only involves one reaction.
