A Life Cycle Assessment (LCA) study of iron ore mining

2019-9-24 · The iron ore production system target of this study is composedof three units: Mining, Processing and Support System. The miningactivity can be described by operations of dismantling, loading andtransportation of ore and waste. Dismantling is done mainly bytractors or dozers and to a lesser extent with the use of explosives.Loaders load trucks with waste and shippers feed conveyor beltswith ore. Waste is transported tofinal repositories exclusively byoff-road diesel trucks, but ore is transported to the processing fa-cilities mostly by electric conveyor belts. Mining activities usetractors, excavators, loaders, diesel trucks and stationary equip-ment such as shippers and electric conveyor belts. The environ-mental aspects of this processing unit are characterized by dieseland electricity consumption, land occupation and transformation,generation of waste rocks that are arranged in waste
