open cast iron ore mining processes involved
An Overview of Steelmaking Process ...
The first metallurgical step involved in this process is to reduce iron ore to metallic iron in a blast furnace, using coke as both a fuel and reducing agent. The produced metallic iron contains a relatively high proportion of carbon (4%) and it is passed to the steelmaking process in the form of liquid at approximately 1450 C, called as 'hot ...

Dec 01, 2016 · Pit lakes form when opencut mining operations cease and the remaining pit fills with ground, surface and rain water. Mine pits, and therefore pit lakes, tend to have high depthtosurfacearea ratios with relatively flat bottoms and steep sides in order to minimise resource extraction costs (, for the purposes of this review we are focussing on large mineral/coal mining pits as in Figure ...

Extraction of Iron | Metallurgy | Blast Furnace and Reactions
This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs. The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag. What happens in the Blast ...

Iron Ore Smelting Process
Mar 13, 2010 · Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed, washed, and transported to the smelter. Here the ore is put into a blast furnace along with limestone and coke and subjected to hot air blasting and heat which converts the ore to molten iron.

Basics of an open pit mine
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.

Karara Iron Ore Mine
Mining is being carried out through conventional openpit methods including drilling, blasting, loading and haulage. The opencast pit is nearly 3,400m long, 1,300m wide and 300m deep. The pit will be gradually stripped of topsoil and overburden to get access to the ore. Drilling is being carried out using hydraulic hammer drills.

Metal and Iron Ore Mining | MCR Safety
The majority of the mining found for these operations is Surface Mining. This form of mining is when minerals are directly removed from the ground surface area. It is also commonly known as "open cast mining", making up the majority of metal ore mining. More than 95% of all nonmetallic minerals involved this type of mining.

Innovations: Introduction to Copper: Mining Extraction
The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfurbearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
