Sand mining - Dredge |
Dredged material is combined with water and pumped through Cyclones
to separate heavy metals (Rutile, Titanium & Zircon) for use in both the
Medical and Industrial fields (Joint replacement or Paint manufacture)
A dredge like this was used to clear Tilligerry Habitat in the 1960's
There was little rehabilitation done by mining companies afterwards
