What are the problems with mining metal ores?

There are many problems with mining metal ores, such as pollution to the surrounding environment. Mining often means cutting down large areas of land so they make the ores a lot more accessible. When they have cleared the existing area of land of all the ore then they leave the holes in the ground uncovered which causes many problems. The land could also collapse. pollution mining means cutting down trees-damages habitats takes lots of energy-expensive limited resources


Why are nodules not mined for ores such as maganese and iron?

Nodules containing manganese and iron are found deep on the ocean floor, which makes mining them technically challenging and expensive. There are also concerns about the environmental impacts of deep-sea mining on fragile ecosystems and biodiversity. As a result, mining companies typically focus on more accessible and economically viable sources of these ores on land.


Why are ores bad to the environment 5 reasons?

It's not, mining it is. Ores are a natural part of the environment. The danger to the environment begins when "civilization" decides it needs the ores and will do almost anything to get them.

This method is often used when the mineral deposits are too deep to be reached with surface mining techniques.
