In Brazil, the state of Pará has received
attention, especially for the production and
processing of kaolin. On the other hand, the
demand for such mineral inputs has led to the
growth of tailings production, which represents
risks, which can be evidenced in recent disasters
involving mining dams. This study consists of a
systematic bibliographical review and aimed at
discussing related methods of processing, kaolin
storage and numerous incidents involving waste
leaks, in order to support actions to detect the
most impacted areas. The results demonstrated
that the processing of kaolin ore in the study
area is carried out via the wet process. Kaolin
tailings storage systems in Barcarena-PA are more
unsafe in relation to alternative disposal systems,
resulting in events of kaolin tailings leaking into
regional water bodies and spreading areas used
for bathing. |
