Drilling for iron ore. Cindy Hadley is a pit technician for Fortescue Mines. She's "a fieldie" working with the iron ore drill rigs. She shares how iron ore is found. She explains how the drill goes down a set distance, for example 30m, and collects a sample every half a metre. She tests the sample of soil to see if the sample is waste or ore ...

2015-1-1 Iron ore was won by drilling and blasting ().As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as “dogger”) allowing mine drivages to be self-supporting. However, he states that in later years where the mining had progressed to the dip, this ...

2014-3-14 Drilling in the benches of open pit mining is done for production of iron ore with mechanized drills specific for each mining method. The main objective of drilling operations is to create a hole of suitable diameter, depth and direction in rock for explosives to be placed for blasting activities.

2014-1-9 The ore from this region is magnetite quartzite which produces high quality pellets with an iron concentration of up to 68 percent. Four pits are active on the site with two of them responsible for most of the output – Central and Korpanga – which have a combined lifespan of 34 years and probable reserves of 480 billion tonnes.

2018-12-31 In 2018, Australia's EDR of iron ore increased by 3% from 2017 to 49 604 Mt (Table 3). Similarly, there was a 4% EDR increase of contained iron to 24 122 Mt (Table 4). EDR attributable to magnetite deposits have decreased by 1%, likely due to re-assessment of projects and inactivity in the magnetite industry.
