To legally operate a mining project in Nigeria, applicants must follow these key steps:
1. Application Submission: Submit a formal request to the Mining Cadastre Office (MCO) with project details.
2. Site Inspection: Authorities conduct technical and environmental assessments.
3. License Approval: Upon compliance, the MCO issues licenses (e.g., Exploration License, Small-Scale Mining Lease).
4. Fee Payment: Pay statutory fees based on license type and mineral category.
A typical sand and aggregate production line includes:
– Primary Jaw Crusher: Processes large raw stones (e.g., feed size ≤750mm, output 50-300 t/h).
– Secondary Cone Crusher: Fine crushing (e.g., discharge size ≤30mm).
– Tertiary Impact Crusher/VSI Sand Maker: Produces cubic-shaped aggregates or artificial sand (0-5mm).
– Vibrating Screens: Multi-layer screening for precise grading.
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE600×900 | 50-160 | 75 |
| Cone Crusher | HPT200 | 90-250 | 160 |
| VSI Sand Maker | S8-1145 | 60-280 | (250+110)×2 |
Q1: How to reduce dust pollution?
A: Install dust covers + spray systems at transfer points.
Q2: Optimal layout for limited space? A: Use vertical shaft impact crushers + compact modular screens.
