Managing and storing waste rock, overburden, mine tailings, and mine water is a key challenge for any mining operation. (Waste rock and overburden are the excess rock and soil unearthed while reaching ore. Tailings are waste materials, often pulverized rock, leftover after the most valuable metals have been extracted from the ore.

Mar 14, 2014· The stripping ratio describes the unit of overburden that must be removed for each unit of crude ore mined. A typical open pit iron ore mine is shown in Fig 1. Fig 1 A typical open pit iron ore mine. On the basis of mining methods, iron ore mining can be broadly divided into two categories namely manual mining and mechanized mining.

is similar to open-pit mining. It is used to collect mineral deposits that are close to the surface in horizontal beds. In strip mining, the overburden is removed, and then lots of small holes are drilled in the rock just over the ore. Explosives are then placed in the holes to break up the rock so that it is easier to find the mineral.

In mining, overburden (also called waste or spoil) is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem that lies above a coal seam or ore body. Overburden is distinct from tailings, the material that remains after economically valuable components have been extracted from the generally finely milled ore.
