Rock or Solid Mine Waste. 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, there is additional waste rock that must be separated from the ore.READ MORE
· 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.READ MORE

The ratio between waste rock and ore production is called the stripping ratio. For example, a stripping ratio of 2:1 means that 2 tonnes of waste rock needs to be mined to mine 1 tonne of ore. Generally, an open pit mine has a higher stripping ratio than an underground mine. Waste rock is often stored close to the mine to minimize transports ...READ MORE
