Effects of Dust Suppressants on Tailing Sand Permeability

Permeability test results using tailing sand and six dust suppressants are presented. Dust suppressant dilution and application rates used were those recommended by the chemical manufacturers for tailing deposits. Each specimen was placed at a dry density of 15.6 kN/m3 (99.2 pcf) and a moisture content of 8% in standard U.S. Bureau of Reclamation (USBR) percolation cylinders. These initial conditions represented average values measured in tailing dam sand beaches.
