<h3>What is open pit mining?</h3>
As the name suggests, open pit mining takes place from surface operations, where there is no need to expand underground. For open pit operation, deposits do not necessarily need to be exposed on the surface.
<h3>What are the stages of open pit mining?</h3>
The processes that involve mining are:
- research
- exploration
- extraction
- transport
- processing
- beneficiation
- and commercialization of the ore.
All these steps are phases of the mining process, according to the National Mining Agency
With this information, we can conclude that Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals.
