What are the mining methods of open-pit mining graphite in Africa?

There are four mining methods for open-pit mining of graphite in Africa:

1. Excavation open-pit mining method: the topsoil and overburden of open-pit graphite ore are excavated, and the ore body is directly excavated, which is suitable for the case of large outcrop of ore body.

2. Blasting open-pit mining method: the rock is broken by blasting technology, and then the stone is transported to the ore treatment plant by loaders and trucks for treatment.

3. Hydraulic impact method: use a high-pressure water gun to wash away the soil and overburden on the surface of the ore body, expose the ore body, and then excavate and transport it.

4. Ore body stripping method: stripping the soil and overburden on the surface of the ore body to expose the ore body, and then collecting and transporting the ore.
