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 ...

Apr 09, 2015 Core drilling is used to define the size and the exact boundaries of mineralization. This is important for determining ore grades being handled, and vital for calculating the reserves of the ore. A strategically placed underground core drilling can also intersect new ore bodies in the neighbourhood.

Even so, when drilling in soft but abrasive ground, drillers find that instead of being flushed and floating up, cuttings tend to stay in the bottom of the drill hole. These cuttings of rock can damage the core bit prematurely. In the case of iron ore, there are even more cuttings clogging up the bottom of the hole and wearing down the bit.

Aug 01, 2012 Typical ground formations in this region are 70 percent iron ore, with bands of chert that are very hard and abrasive. These conditions require a very free cutting bit to stay sharp and achieve good production, as well as an abrasion-resistant matrix to attain acceptable bit life.

Diamonds, one of the hardest naturally-occurring materials on earth, play an important role in exploration drilling. These precious stones are the key component of a core drill, where they are sprinkled throughout the drill bit. As the drill bit wears down, more diamonds are exposed, allowing the drill to continue cutting its way through the rock.
