Published by the American Geosciences Institute Environmental Awareness Series Modern mining operations actively strive to mitigate potential environmental consequences of extracting metals, and such operations are strictly regulated in the United States

With time, mining have expanded and increasing amounts of fossil fuels e g coal and metals e g iron were extracted in quantities generally commensurate with man power available and thus with The sand fraction with no value silica, hematite, carbonates is returned to the beach in the rear of extracting

Extraction of Metals Extraction of Iron Iron is extracted from its ore in the blast furnace The main iron ore is called haematite Haematite is ironIII oxide Fe 2 O 3 The iron ore contains impurities, mainly silica silicon dioxide Limestone calcium carbonate is added to the iron ore which reacts with the silica to form molten calcium silicate in the blast furnace

Subsequent increase in temperature to 1200°C improves the extraction of iron In the indirect reduction of slag at temperatures above its melting point, metallic iron is mainly concentrated at the outer surface of the product, forming large inclusions that are easily extracted by magnetic separation

Ancient iron production refers to iron working in times from prehistory to the early Middle Ages where knowledge of production processes is derived from archaeological investigation Slag, the byproduct of iron working processes such as smelting or smithing, is left at the iron working site rather than being moved away with the product It also weathers well and hence it is readily available
