Abstract

The invention relates to a method and system for the environmental remediation of materials that are contaminated with heavy minerals, such as heavy metals. The invention finds utility in removing heavy minerals from materials such as soils, sediments, mine tailings and ores. The invention provides a means for removing heavy minerals from contaminated materials without the use of water while reducing the generation of dust. Thus, the invention provides an environmentally friendly method for the remediation of sites that are contaminated with heavy minerals.

IPC Classes  ?

• B03B 4/04 - Separating by pneumatic tables or by pneumatic jigs using rotary tables or tables formed by travelling belts
• B07B 4/08 - Separating solids from solids by subjecting their mixture to gas currents while the mixtures are supported by sieves, screens, or like mechanical elements
• B03B 4/02 - Separating by pneumatic tables or by pneumatic jigs using swinging or shaking tables
• B07B 7/086 - Selective separation of solid materials carried by, or dispersed in, gas currents using centrifugal force generated by the winding course of the gas stream
• B03B 9/00 - General arrangement of separating plant, e.g. flow sheets
• B03B 9/06 - General arrangement of separating plant, e.g. flow sheets specially adapted for refuse
• B07B 7/083 - Selective separation of solid materials carried by, or dispersed in, gas currents using centrifugal force generated by rotating vanes, discs, drums, or brushes
• B07B 1/10 - Screens in the form of endless moving bands
