This technique uses Iron Sand to create a gigantic sphere of branching spikes. The user first creates two masses of Iron Sand of opposing magnetic fields and then merges them together. This causes the magnetic forces to instantly increase and the repellent force created by the two opposing magnetic fields scatters the Iron Sand across a vast area. The Iron Sand spreads in spikes that branch ...

Ironsand, also known as iron-sand or iron sand, is a type of sand with heavy concentrations of iron.It is typically dark grey or blackish in colour. It is composed mainly of magnetite, Fe 3 O 4, and also contains small amounts of titanium, silica, manganese, calcium and vanadium.. Ironsand has a tendency to heat up in direct sunlight, causing temperatures high enough to cause minor burns.

Rainbowing is often the best method for discharging huge quantities of sand in shallow locations close to shore, for land reclamation projects or beach replenishment. Since rainbowing does not require floating or submerged pipelines, boosters or landlines, it is often the most economical, cost-efficient method.
The Project consists out of the capital dredging works of the quay 2 area in order to deep the existing berth pockets OSV Berth and Iron Lady. With existing depths to CD of -4/-5 m on average, both pockets should be deepened to the following depths. • OSV Berth Pocket: 8.2 m • Iron Lady Berth Pocket: 7.6m

available to drive the dredge pump, the reclamation dredger was only used when the distances to the disposal site were short. In the other cases barges were used or the dredger was modified. As the sand pumps became able to withstand higher pressures, the transport distances and pump capacities were increased. 4.5 Working method
The Sigatoka iron sand mineralisation is easily accessible and mining is expected to employ low-cost dredging methods commonly used in the mineral sand mining industry.

Different sorts of soil are subject to dredging. At different locations dredged solids may differ strongly in density, size, shape and consistency. It is a very different experience to dredge the iron ore of density round 4700 kg/m3 or the sand of density 2650 kg/m3. If clay (a typical particle size is in an order of microns) is dredged it is
A trailing suction hopper dredger is a large ocean going vessel. When the vessel starts dredging, the ship reduces its speed to some 1 to 2 knots and then lowers the suction pipes on both sides of the ship all the way to the seabed. Sand pumps transfer the sand dredged up by …
