Mining-Mining -Surfacemining: It has been estimated that more than two-thirds of the world’s yearly mineral production is extracted by surfacemining. There are several types of surfacemining, but the three most common areopen-pit mining, stripmining, and quarrying. These differ from one another in theminegeometries created, the techniques used, and the minerals produced

Open-pit miningof direct shipping hematiteore, 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 theoreis railed to Nouadhibou in trains of up to 220 cars, each carrying 84t
Open pit miningis a technique used to extract copperorenear the earth's surface.Open pit miningis the most widely used technique ofminingcopper today. It is accomplished by creating and using benches or terraces to gradually reach deeper under the earth's surface. Undergroundminingis used when the copperoreis not near the earth's

Mining-Mining - Underground mining: When anyorebody lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover theorethrough surfaceminingbecomes prohibitive, and underground techniques must be considered. Counting against undergroundminingare the costs, which, for each ton of material mined, are much higher underground than on the

Mining– extensive drilling and blasting is required to extractoredeposits from the igneous complex. Once the rock has been blasted, either a hydraulic or rope shovel or a front-end loader is used to load theoreonto one of Foskor’s 180-ton haul trucks so that the rocks (up to 1.2 metres in diameter) can be transported to the crushers

Mining. For lower-grade deposits located near the surface, theopen-pitmethod is the most practical for theminingof large tonnages of material. Large track-mounted drills prepare theorefor blasting, and the brokenoreis hauled to theore-dressing plant by truck (at up to 150 tons per load) or conveyor. In undergroundmining, vertical
