Tantalum mining: A source of wealth and challenges. The rise of Rwanda's tantalum industry has been driven by a combination of artisanal and small-scale mining (ASM) and efforts to transition to industrial-scale production. While ASM remains prevalent, initiatives to modernize the sector have led to greater efficiency, safety, and output.
