Iron ore | BHP

How is iron ore mined? Iron ore undergoes a series of processes from pit to port before export. First, we explore the geology of the region to find the best iron ore prospects for our mining operations. Once the ideal site has been chosen, the ore is drilled and blasted. It is transported to the primary crusher for processing.

Metal ore mining in Europe - Mineral Processing

On a world scale, the quantities produced are low. Since the iron ore is extracted in underground mines (Fig. 2), mining costs are hardly competitive compared to the open pit mines of, for example, Australia or Brazil. As a consequence, the low iron ore prices have been very problematic for mining companies.

Open-Pit Mining Methods

Open-Pit Mining Methods. Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping.

Open-pit mining - Wikipedia
