Pollution of water bodies results from three primary factors: sedimentation, acid drainage, and metals ...
Through revegetation, compensation plans, education, inspections and environmental assessments, IOC aims at preserving the natural resources in the boreal forest and marine environment it finds itself part of. Environmental management at IOC looks at the entire mining life cycle and works to reduce impacts on the land, air, water and people where we work.
Regarding the environmental impact on 'Mineral Extraction' (0.07%), one would expect to observe a higher impact considering the high amounts of iron ore consumed; but this was not the case. This could indicate that impact on mineral extraction was low in comparison to impacts that are directly associated with the production process of sinter.
