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, ground excavation, and from equipment t

Iron ore pollution in Mandovi and Zuari estuarine

Iron ore was mined from the banded iron formations of Goa, India, and transported through the Mandovi and Zuari estuaries for six decades until the ban on mining from September 2012. Here we focus on the environmental magnetic properties of sediments from the catchment area, upstream and downstream of these estuaries, and adjacent shelf during

Modern air pollution control for iron ore induration

The iron ore induration or pelletizing process emits particulates, sulfur dioxides (SOx), nitrogen oxides (NOx) and other pollutants depending on trace elements in the orebody and fuel. Typical emission levels for these compounds during induration will be outlined, and corresponding options for pollution control equipment described.
