Damen Dredge Pump Put to Use in South Africa

On the Western coast of South Africa, high grade heavy mineral sediment layers are found on the seashores.

Located just below a layer of fairly standard quartz sand, this heavy mineral sand can be mined. The material, which is also called HMS, has a relatively high specific gravity of 2.8T.m3 in situ.

Until recently, the mining operations in the surf zone were done conventionally using excavators and trucks. Yet they have to be relocated every time the tide comes in.

The DOP250 however can mine continuously when attached to an amphibious excavator. The DOP250 mines heavy mineral sand at a max dredging depth of 10 m. The heavy sand mixture is pumped in a concentration up to 25% over a distance of 250 m over a cliff of 15 m in height.

On shore the processing plant separates the valuable minerals from the quartz sand and stones.

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
