Mar 14, 2014· Mining techniques usually consist of two types based on excavation methods. These are surface mining and underground mining (sub surface mining). Iron ore is almost exclusively mined by surface operations. The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods.
Open-pit mining or opencast mining refers to a method of extracting rock or minerals from the earth by their removal from an open pit or borrow. It is a form of surface mining. The term is used to differentiate this form of mining from extractive methods that require tunneling into the earth, like longwall mining.
Mining stocks rise as iron ore prices climb - CNBC. The Carajas Open Cast Iron Ore mine is the largest iron mine in the World, estimates say the site can be mined at today's rates for another 400 years.
A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.
INTRODUCTION TO MINING 1.1 MINING'S CONTRIBUTION TO CIVILIZATION Mining may well have been the second of humankind's earliest endeavors— granted that agriculture was the first. The two industries ranked together as the primary or basic industries of early civilization. Little has changed in the
mining: Open-pit mining Deposits mined by open-pit techniques are generally divided into horizontal layers called benches. The thickness (that is, the height) of the benches depends on the type of deposit, the mineral being mined, and the equipment being used; for large mines it.
This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western U.S. mining operations. All costs listed are in 2012 US$.

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.
Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine - a pit, and the ...

Cast Blasting When overburden is removed from a coal or mineral deposit it is generally cast to a waste dump by draglines, or removed by loaders and trucks. Cast blasting is the controlled placement of overburden into the previously mined cut resulting in a reduced volume or overburden material for the dragline to handle.
Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
