MINING AND QUARRYING

mining is done using the open cast method. Magnetite, which is the ore variety in Kudremukh, is of low grade having iron concentration to the tune of 33 to 38 percent resulting in generation of more waste (62 to 67 percent of the total ore mined). Out of 4605 hectares of mine lease area sanctioned till 1999, an area of 450 hectares has

Equipment Selection for Surface Mining: A Review

A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.
