bauxite mining process in cameroon

Bauxite mining in Cameroon is still in its early stages, but the country has significant deposits, particularly in the Minim-Martap and Ngaoundal areas in the Adamawa Region. Here’s an overview of the bauxite mining process in Cameroon:

1. Exploration & Feasibility Studies
– Geological Surveys: Identify bauxite reserves through drilling and sampling.
– Feasibility Studies: Assess economic viability, environmental impact, and infrastructure needs.
– Licensing: The government grants mining permits (e.g., Cameroon Alumina Limited, a subsidiary of Dubai’s Mubadala Investment Company, holds rights to Minim-Martap and Ngaoundal deposits).

2. Site Preparation & Infrastructure Development
– Land Clearing: Removal of vegetation and topsoil.
– Road & Rail Construction: Transport infrastructure is crucial (e.g., linking deposits to the railway from Mbalam to Kribi port).
– Power & Water Supply: Establishing energy sources for mining operations.

3. Mining Methods
Cameroon’s bauxite is typically extracted via:
– Open-Pit Mining (most common):
– Topsoil removal.
– Drilling and blasting (if needed).
– Excavation using loaders and haul trucks.
– Strip Mining: Used for shallow deposits.

4. Processing & Refining
– Crushing & Washing: Bauxite ore is crushed and washed to remove impurities like clay and silica.
– Beneficiation: Further refining to improve alumina content.
– Currently, Cameroon lacks large-scale alumina refineries, so most raw bauxite is exported (mainly to China, UAE).

5. Transportation & Export
– Bauxite is transported via truck or rail to ports (e.g., planned expansion of Kribi Po.
– Export primarily goes to countries with alumina refineries.

6. Environmental & Social Concerns
– Deforestation and habitat destruction.
– Water pollution from mine runoff.
– Land disputes with local communities (e.g., concerns from residents near Minim-Martap).
– Government aims for compliance with sustainable mining standards.

Key Projects in Cameroon
1. Minim-Martap & Ngaoundal Deposits (estimated 550+ million tons of high-grade bauxite).
2. Cameroon Alumina Ltd (CAL) Project – Expected to produce ~5 million tons/year once operational.
