Extensive development of low grade ores and open pit mining began after World War 11, and a relatively new process, agglomeration, then began to yield an iron ore concentrate that contained about sixty-five per cent iron compared with fifty-six to sixty per cent from the average underground workings of the high grade ore.

The iron ore project would have spanned five departments in the centre-west part of the country and it was set to generate $1.4 billion in exports annually over the 20 years of its life cycle.
In the previous topic, we saw which are some of the advantages that can make the surface open pit mining methods superior method compared to the underground mining. However, underground mining has its own advantages. And finally, the ultimate decision to mine from the surface or from underground comes down to the specific characteristics of the deposit.

This paper investigates the application of the neural network in a run of mine ore stockpile in Choghart Iron Mine of Iran. While a significant amount of high grade stockpile at Choghart mine, near the open pit, is an environmental hazard, it is also potential source of high grade ores.
Open-pit iron mining is environmentally unsound Unlike some of the underground iron mining that was common a century ago, open-pit iron mining has a larger and more destructive impact on the environment near the mine site.
Conducted a scoping study for Cobre Las Cruces S.A. to establish viability of mining certain parts of the ore body from underground instead of from the planned open pit. The trade-off point between underground mining and open pit extraction was roughly determined.

Open-pit mining of direct shipping hematite ore, using rotary drills, small shovels and trucks, commenced in 1963 at F'Derik, Rouessa and Tazadit. Primary and secondary crushing is done at Tazadit and the ore is railed to Nouadhibou in trains of up to 220 cars, each carrying 84t.
Although open pit mining (link to mining solution page) contributes about 85% of all mineral mining, it is one of the most environmentally taxing. About 73% of extracted rock goes to waste. Meanwhile, underground mining wastes only 7% of the extracted rock but is more expensive (Hartmann and Mutmansky, 2002).
