The choice of mining method for extracting ore from the earth's surface depends on various factors related to the ore itself. These factors include whether the ore is stratiform or podiform, its grade (whether high or low), and its depth below the surface.Most chromium ore is found abundantly in stratiform deposits within layered intrusions, with notable …

Chrome ore usually exists in the earth's crust in the following forms: chromite, which is a dark, black-to-brown-black mineral composed of chrome, iron, and oxygen. It has an affinity for oxygen and iron, so the minerals with industrial value are generally chrome-magnesium spinel or chrome-iron spinel.
