Method of mining tin and Columbite
Tin and Columbite are mined by a method called open cast method. The process of mining is as follows
- Explosives are used to remove the overburden rocks
- A powerful machine called a dragline is then used to pile the tin into a heap
- A monitor is then used to direct a strong jet of water towards the heap
- The water washes the soil out through a series of sluice boxes
- The tin ore sinks to the bottom of the sluice boxes while the water carries the dirt away
- The tin concentrate now formed is later sent to the factory for smelting
- Limestone: Limestone is a sedimentary rock mineral found in Ewekoro and Shagamu (Ogun state), Ukpilla (Edo state), Calabar (Cross River state), Nkalagu (Anambra state),Benue and Sokoto states.
