Mining of Iron Ores IspatGuru

14/3/2014· Fig 1 A typical open pit iron ore mine. On the basis of mining methods, iron ore mining can be broadly divided into two categories namely manual mining and mechanized mining. Large iron ore mines are mechanized mines while manual mining methods are employed in the small mines. Manual mining method is normally limited to float ores. Mining of reef ore is also being done

Open-Pit Mining Definition Anglo American

Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Open-pit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. This surface mining technique is used when mineral or ore deposits are found relatively close to the surface of the earth

World's Largest Open Pit Iron Ore Mine

Sometimes called the "Grand Canyon of the North," the Hull Rust Mine is the biggest open pit iron ore mine in operation in the world. At the present time, it is more than three miles long, two miles wide, and nearly 540 feet deep. It's operated by the Hibbing Taconite Company. Taconite is low-grade iron ore and explanation about how the ore is being processed

The worlds deepest, biggest and deadliest open pit mines

The biggest iron mine. The world’s biggest open pit iron mine can be found near Hibbing, Minnesota. At its maximum, the area covered by the Hull Rust open pit mine is five miles (8km) long, 2 miles (3,2km) wide and 535 feet (180m) deep. It looks like a man-made Grand Canyon of over 2,000 acres (8,1km²). The first iron ore extractions were made here in 1895. Beginning as a small underground

Basics of an open pit mine Mine Engineer.Com

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal. In a hard rock mine, the bottom of the pit would be the

Iron Ore production in the Pilbara Rio Tinto

Iron Ore production in the Pilbara Mine operations Drill and Blast Areas for open-pit mining are selected using the mine plan. Identified areas are tagged, and then holes are drilled in an appropriate pattern by rigs. The drill holes are filled with an explosive, most often ANFO (Ammonium Nitrate/Fuel Oil) and then charged. The resulting blast breaks the material to a size required for digging

Mining LKAB

Open-pit mining. Ore is extracted from LKAB's surface mines by means of bench mining. The method is based on mining the ore in descending levels through drilling and blasting. The thickness of the slabs, known as the bench height, is 15 metres, and the slabs are worked downwards. Bench mining is an effective and well established mining method
