1.Backgroun introudction
Diamond mining in the Democratic Republic of Congo (DRC) is indeed a complex topic. It's a crucial link in the global diamond supply chain, but also presents significant social and environmental challenges. Let me outline the key points:
I. Scale and Status of Mining The DRC is the world's largest industrial diamond producer, accounting for 70% of the country's total diamond production. In 2024, diamond production reached 16 million carats, representing 3% of global production. Diamonds are mainly found in the Kasai River basin in the north-central region,
primarily alluvial diamonds. Major mining areas include Mbandaka, known as the "diamond capital."
II. Mining Methods and Supply Chain **Artificial Mining:** Dominant method, approximately 70% of diamonds are extracted by local miners using simple tools, then the slurry is transported in containers. This method is inefficient and risky, but supports a large number of livelihoods.
Industrial Mining:Operated by large mining companies (such as Miba), employing modern technology, but accounting for a relatively small proportion.
Supply Chain: After mining, diamonds are usually exported directly without refining, resulting in a short supply chain and low added value.
To date, our company has exported five sets of diamond dredger to the Democratic Republic of Congo. The diamond dredger can be divided into the jet suction type diamond dredger,bucket chain diamond dredger and cutter suction diamond dredger. Our most successful cases in the DRC congo is bucket chain diamond dredger. why the bucket chain diamond dredger is most popular? Because the bucket chain diamond dredger are mainly used in the local rivers with a lot of big pebbles and stones. The bucket of China diamond dredger is easy to dredge the sand and stone from the river beds.
