The estimated greenhouse gas emissions were 11.9 kg CO2 e for mining and processing 1 tonne of iron ore. The embodied energy values were 153 MJ/t ore for iron ore. The results showed that loading and hauling made the largest contributions (approximately 50%) to the total greenhouse gas emissions from the mining and processing of iron ore.

Optimized design of drilling and blasting operations in open pit …
Drilling and blasting are the two most significant operations in open pit mines that play a crucial role in downstream stages. While previous research has focused on optimizing these operations as two separate parts or merely in a specific parameter, this paper proposes a system dynamic model (SDM) for drilling and blasting operations as an interactive system.

Blastability and Ore Grade Assessment from Drill
Positioning of the holes is controlled by the operator but drilling and logging of drill parameters are done automatically. Drilling is done using extension tubes of 6 m length and a bit diameter of 6″ (152 mm). A 4.16 revision control system was installed in the rigs and a sample interval of 0.05 m was set to monitor the information.

After the soil and overlying rock are cleared, the ore is drilled and blasted. The portion of the ore body to be removed is first drilled by using rigs in an appropriate pattern. The drilled holes are then loaded with explosive mixtures, charged and blasted. The resulting blast breaks the material to a size required for digging.

Each of the holes is detonated just a millisecond apart, resulting in a pile of crude iron ore that is broken apart to a minus 2 m x 2 m size. The wide holes in the ground created by drilling, blasting, and ore removal are referred to as 'open pits'. Following blasting, the fractured ore is known as run of mine (ROM) ore.

Over 300 minerals contain iron but five minerals are the primary sources of iron ore. They are (i) magnetite (Fe3O4), (ii) hematite (Fe2O3), (iii) goethite (Fe2O3.H2O), (iv) siderite (FeCO3), and (v) pyrite (FeS2). The first three are of major importance because of their occurrence in large economically minable deposits.
