Early iron smelting was accomplished using charcoal- fueled furnaces known as bloomeries. Iron's Impact: Iron tools and weapons were harder and more durable than bronze, leading to transformative changes in agriculture, construction, and warfare. Iron was the foundation of empires like the Roman Empire, as it enabled the construction of
Open-pit mining differs from quarrying (with the possible exception of iron ore) in that the valuable mineral constitutes only a small proportion of the total tonnage of rock produced. In quarrying, the rock itself is the valuable commodity, with virtually all of the raw rock that is won being processed (often only by crushing and screening) to ...
