What is Overburden in Mining?
2 天前 · Overburden refers to the rock or soil layer that needs to be removed in order to access the ore being mined. Overburden is also referred to as spoil or waste. Overburden is removed from surface mining and does not contain toxic components, unlike tailings, which is another type of underground mining waste. Interburden, a related term, refers to ...

2008-9-1 · Removal of overburden to access the ore can pose major problems in storage and reclamation. The stripping ratio (waste-to-ore) for surface mining of metal ores generally ranges from 2:1 to 5:1, depending on local conditions. The iron ore is predominantly mined by opencast mining throughout the country.

Mine Waste Transfer and Disposal Methods - Mine Tailings ...
Open pit mining has several stages of waste. First, to access the actual seams or veins of ore, the top layers of rock, or overburden, must be removed. Once the overburden has been removed, the seams can be extracted. When extracting the seams, the additional waste rock will be removed to get to the actual ore, called gangue.

The dilution by waste rock is caused above all by irregular ore boundaries, or poor strength of the surrounding rock. Several different mining methods are used for underground mines, depending on the character and value of the ores. For smaller ore bodies with a high ore value, backfilling is often applied, which brings small ore losses, small ...
