Open-pit mine planning is a key process in the definition of mineral reserves and their efficient removal. Ore in open-pit mines is extracted bymining sequential pits called pushbacks. Pushbacks need to satisfy complex geometrical constraints to ensure the efficient usage of equipment. To date, no algorithms that both account for those constraints and …
Since the hardness of graphite ore is generally medium-hard or soft, and the grade is generally between 2% and 10%, it usually adopts three-stage open circuit, two-stage open circuit or one-stage crushing process. Ensure that the graphite flakes are not damaged and the quality of the concentrate meets the requirements. 2.

The reason a large-scale open pit mine has never been attempted in the area has to do with the features of the iron deposit. The deposit lies at a 70 degree angle and is buried an average of 350 feet from the surface. The ore is only about 20 per cent iron, but is magnetite, which can be crushed and extracted with high-powered magnets.
