Unloaders had handled several billion tons of iron ore. 1 Boyum, "The Saga of Iron Mining in Michigan's Upper Peninsula," p.13. The first dock built specifically for iron ore was erected by the Lake Superior Iron Company at Marquette in 1857. 2 John A. Burke, "Barrels to Barrows, Buckets to Belts: 120 Years of Iron Ore Handling On the Great
Sinter is the primary feed material for making iron in a blast furnace. According to the U.S. Environmental Protection Agency, the sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace. ...
Ore car dumping Once the train arrives at the port the ore cars go through the car-dumper. The ore cars are rotated and the ore flows out into bins and then is discharged onto conveyors. Stockpile The ore is stockpiled according to product type and the quality control plan. The travelling stackers create 250m long stockpiles. Rotary bucket-wheel
The iron ore sintering process is the main source of VOCs emission in the iron and steel industry, and its VOCs emission accounts for about 69.6% . The organic compounds in the solid fuel and the oil components from the raw materials such as rolling oily sludge are pyrolyzed in the preheating layer (150–900 °C) to produce VOCs [ 9, 10 ].
