What Effect Does Mining Iron Ore Have On The Environment

Environmental impact of iron ore mining - Wikipedia

The main sources of emissions during both the construction and operation phases include the products of combustion such as nitrous oxide, carbon dioxide, carbon monoxide, and sulfur dioxide and fugitive dust from the operation of equipment. The main sources of combustion-related emissions during both the construction and operation phases are related to diesel generators, fuel-oil boilers, and from on-site road traffic. Fugitive dust emissions can occur during land clearing,
