CLEAN : De Beers launches Nambian offshore mining exploration

The video discusses the unique aspects of marine mining, highlighting the industry's rapid changes and the need for innovation. It describes the challenges of extracting resources from large, non-homogeneous areas underwater and emphasizes the importance of resource development and preservation. The process of handling gravel and sorting diamonds is also explained.

What is a key difference between traditional mining and marine mining?

• Marine mining involves resources located underwater.

• Traditional mining is more innovative.

• Traditional mining is less challenging.

• Marine mining is conducted on land.

Why is resource development critical in marine mining?

• Due to the small size of the resource area.

• Because resources are homogeneous.

• Because resources are easily accessible.

• Due to the large and patchy nature of the resource area.

How is the area of marine resources described?

• As a small and homogeneous area.

• As a vast and patchy area.

• As a large and homogeneous area.

• As a small and concentrated area.

What is the primary focus when gravel is brought up to the ship?

• To store gravel for future use.

• To return all materials to the seabed.

• To sort and collect diamonds.

• To discard all materials.

What is the significance of sorting diamonds into different categories?

• To determine the quantity available in a specific area.

• To ensure they are not used.

• To mix them with other minerals.

• To discard them as waste.
