Iron Ore - Mineral Technologies

Hard rock hematite deposits often require a combination of milling, screening and on occasion, fine classification to prepare a finely sized (-1.0mm), liberated feed for beneficiation by gravity separation. This is typically followed by re-grinding of the tailings to liberate more hematite for further iron unit recovery by magnetic separation.

Hardrock Mining | National Wildlife Federation

Landslides - California Department of Conservation

A rock fall is a landslide where a mass of rock detaches from a steep slope by sliding, spreading or toppling and descends mainly through the air by falling, bouncing or rolling. Intense rain, earthquakes or freeze-thaw wedging may trigger this type of movement. Rock falls occur on steep slopes of hard, fractured rock.

continental drift | National Geographic Society

In the process of seafloor spreading, molten rock rises from within the Earth and adds new seafloor (oceanic crust) to the edges of the old.Seafloor spreading is most dynamic along giant underwater mountain ranges known as mid-ocean ridges. As the seafloor grows wider, the continents on opposite sides of the ridge move away from each other.
