Mining Waste Products. The types of waste materials generated are dependant upon the type of mining activity. Around the Fal Estuary there have been effectively three main types of mining activity: (1) the recovery of cassiterite from the river sediments (so called tin streaming or placer mining); (2) the underground and opencast mining for metal (hard rock mining); and (3) opencast mining for ...

Contaminants are most likely to escape from waste rock piles, since they are less contained than contaminants in a pit. Careful monitoring is necessary, to ensure that waste products are not allowed into the environment. [1] Case Studies. Bayan Obo Mine. The primary product of this mine is iron, with rare earth elements as secondary products.

However, gold is produced in much smaller quantities, so the total environmental footprint for global gold production is smaller than some other commonly used metals, including steel, copper and aluminium. The stages that contributed the most to gold's environmental impact were mining and comminution (crushing and grinding of the ore).
