drilling and blasting in iron ore mines

Iron Ore Mining

EXTRACTING IRON FROM IRON ORE USING BLAST FURNACE: Extracting iron from its ore requires a series of steps to be followed and is considered as the penultimate process in metallurgy. The steps need the ore to be concentrated first, followed by the extraction of the metal from the concentrated ore after which the metal is purified.

The Pilgangoora project consists of open-pit mining services including drilling and blasting and loading and hauling, and the extension is expected to generate approximately A$70 million ($51 million) in revenue for MACA over the 12-month term through to November 2022. MACA's work in hand position as of September 21 is A$3.1 billion, it says.

iron ore drilling and blasting

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.

Iron Ore Mining

Kolomela Iron Ore Mine, Northern Cape

Iron ore mining and processing at Kolomela Kolomela employs the conventional open-pit mining method involving drilling, blasting, shovel-and-truck loading and hauling. The extracted ore from the mine is sent to the nearby processing plant. The ore undergoes primary, secondary and tertiary crushing at the plant.

From mine to port

Drifting: Construction of transport tunnels, or drifts, into the ore body. Production drilling: Using a remote controlled drilling rig, long holes are drilled upwards through the ore body in a fan-shaped pattern, known as a fan cut. Blasting: A creamy-textured explosive is pumped into the holes. Blasting is done every night.

Iron Ore Company of Canada

We have a high-quality iron ore reserve and long mine life. In 2018 we opened a new pit, the Moss pit, at our existing mine site in Labrador. This development will extend the life of our IOC operation, reduce operating costs and sustain production of our quality grade iron concentrates and pellets.
