  • Patent number: 6561359
    Abstract: An apparatus and method for removing lightweight particulates during processing of a primary material. The apparatus includes a classification tank having an inlet, an outlet and a plurality of settling stations located therebetween. A slurry of fluid and particles is introduced into the inlet and directed towards the outlet. As the slurry traverses along the classification tank, particles come out of suspension at the settling stations according to weight and to a lesser degree, density. The composition as well as the quantity of particles at the settling stations is periodically inspected. If particles deposited at a particular settling station are more or less the same size, and if they have accumulated in sufficient quantity, they are discharged to a flume which directs them to preselected collection areas.

  • Patent number: 4783253
    Abstract: A process for treating radioactive contaminated soils to remove radioactive metal oxide contaminants therefrom comprises creating a suspension of particles of the soil in a column of water, alternately forcing fresh water in the column upwardly to force ligher soil particles upwardly in the column and allowing heavier particles to gravitationally settle in the bottom of the water column. The heavy particles comprising radioactive metal oxides are collected and handled for radioactive waste material storage. The aqueous slurry of lighter soil particles is directed to a separator for removing substantial amounts of water after which the particles are directed to a conveyor and spread out to a substantially uniform thickness and detected for any radioactivity. Portions of material in which radioactive particles are detected ar diverted and the uncontaminated soil material is recovered.

    Abstract: A wash box for separating materials produced in, for example a mining operation, into fractions of different densities. The machine is divided vertically into compartments, including at least one stratification compartment and at least one reject compartment, the raw material being delivered onto the grid, the level of water in the compartments being higher than the grid. Vertical pulsations are applied to the water in the compartments, causing the water to travel through the perforations of the grid. The pulsations applied to the stratification compartment are effective to stratify the material on the grid, movement of the water through the wash-box tending to carry the lighter fraction from the wash-box while the pulsations applied to the reject compartment determine the rate at which the heavier fraction reject material falls from the grid plate into a reject extraction chamber adjacent to the reject compartment.
