Abstract
Official abstract text for this publication.
An apparatus for collecting mineral particles in a slurry or the tailings is disclosed. The apparatus may take the form of a filter, a conveyor belt or an impeller to be used in a processor to collect mineral particles in the slurry, or in a tailings pond to collect mineral particles in the tailings. The filter, conveyor belt or impeller has a collection area made of or coated with a synthetic material having a functional group, either anionic or cationic to attach to the mineral particles. Alternatively, the synthetic material has hydrophobic molecules to render the collection area hydrophobic. When the mineral particles in the slurry or tailings are combined with collector molecules, the mineral particles also become hydrophobic. The hydrophobic mineral particles are attracted to the hydrophobic collection area. The filter, conveyor belt and impeller may have a plurality of passage ways in order to increase the contacting surfaces.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus comprising: a collection area comprising collection surfaces configured to contact with a mixture comprising water and valuable material, the valuable material comprising a plurality of mineral particles; and a synthetic material provided at least on the collection surfaces, the synthetic material comprises plurality of molecules comprising a functional group configured to attract the mineral particles to the collection surfaces, wherein the f…
