Abstract: The process for removal of metal-contaminated sediment includes dredging the sediment and removing large objects from the sediment, then removing smaller objects such as shell fragments with a first course screen. The remaining sediment slurry is processed through at least two screens covering a range of mesh sizes to separate the solids into three size/mesh fractions. Water extracted during the separation is processed through a series of hydrocyclones to separate any remaining solids and to allow the water to be recycled. The largest fraction of solids, the "sand fraction" has a low concentration of the metal and requires no further processing. The smallest fraction, which has passed through a mesh corresponding to the size of the most basic form of the metal ore, enters a screw classifier for dewatering after which it is appropriate for direct smelter recycling.
