The main objective of this paper is to present the main impacts caused by mining activities in Pará municipalities. A documentary and bibliographical analysis was necessary for the textual elaboration, in addition to field research in the study area. We can observe that mining is an important productive activity, but has caused significant changes in Pará territory, as well as in economy and in the environment, and the way of life of local populations.
