There are several methods used to mine minerals in Nigeria, including:
1. Open-pit mining: This method involves the extraction of minerals from an open pit or surface excavation. It is commonly used for minerals that are close to the surface and can be easily accessed.
2. Underground mining: This method involves the extraction of minerals from underground tunnels or shafts. It is used for minerals that are located deep underground and cannot be accessed through open-pit mining.
3. Dredging: This method involves the extraction of minerals from underwater deposits using a dredge. It is commonly used for minerals found in rivers, lakes, and coastal areas.
4. Artisanal and small-scale mining: This method involves the manual extraction of minerals by individuals or small groups using basic tools and equipment. It is commonly used in rural areas where larger mining operations are not feasible.
5. Hydraulic mining: This method involves the use of high-pressure water jets to extract minerals from the ground. It is commonly used for minerals that are found in loose or unconsolidated deposits.
6. In-situ leaching: This method involves the extraction of minerals by injecting a leaching solution into the ground to dissolve the minerals and then pumping the solution to the surface for processing. It is commonly used for minerals that are not easily accessible through traditional mining methods.
Overall, the methods used to mine minerals in Nigeria vary depending on the type of mineral being extracted, its location, and the scale of the operation.

Open-Pit Mining:
- Digging large, open pits or quarries to extract minerals near the surface.
- Used for minerals such as iron ore, limestone, and coal.
Underground Mining:
- Excavating tunnels and shafts to reach mineral deposits deep beneath the surface.
- Methods include:
- Room-and-pillar mining: Creating rooms and supporting them with pillars of mineral.
- Longwall mining: Using a continuous miner to cut coal in a long, narrow face.
Hydraulic Mining:
- Using high-pressure water jets to break up and wash away soil and rocks to expose minerals.
- Commonly used for gold and diamond mining.
Placer Mining:
- Sifting through loose sediments, such as sand and gravel, to find minerals like gold and diamonds that have been weathered and deposited in riverbeds or beaches.
Artisanal Mining:
- Small-scale mining operations that involve manual labor and simple tools.
- Often used to extract gold and other minerals from alluvial deposits or shallow surface outcrops.
Mechanical Mining:
- Using machinery such as bulldozers, excavators, and trucks to remove overburden (waste material) and extract minerals.
- Typically used in open-pit mining.
Other Methods:
- Heap leaching: Using a chemical solution to dissolve minerals from crushed ore placed on a large heap.
- In-situ leaching: Flooding an underground ore body with a chemical solution to dissolve minerals.
- Solution mining: Injecting water or a solvent into underground salt deposits to dissolve and extract the salt.
- Digging large, open pits or quarries to extract minerals near the surface.
- Used for minerals such as iron ore, limestone, and coal.
