Abstract
The objectives of this study were to (1) determine the state of the art for the control effectiveness of various chemical dust suppressants, (2) field test the effectiveness of the dust suppressants, and (3) develop technical guidelines for selecting and implementing cost-effective tailings pond dust control programs. Chemical stabilizers evaluated under field conditions were coherex, calcium lignosulfonate, nalco 656 and 655, and magnesium chloride. Testing in the field utilized a portable field in situ wind tunnel. The wind tunnel was placed on the tailings surface, and simulated wind speeds up to 80 mph were used to determine wind erosion threshold velocities. Emission rate testing was performed with the wind tunnel through the use of a realtime cascade impactor. A control cost-effectiveness evaluation was performed to determine how efficient the chemical stabilizers were on a dollars expended per acre basis.
