Effects of iron-ore mining and processing on metal

This study has demonstrated the contrasting effects of iron-ore mining and processing on metal release, speciation, and bioavailability in an impacted tropical coastal lagoon. On one hand, iron-ore mining and processing constitute potential sources of metals to the lagoon, on the other hand they also contribute to reducing metal bioavailability.
