Asarco Uses Terramac® RT9 in Tailings Ponds for Dust Control

Copper producer, Asarco is the first mining company to use a Terramac® RT9 rubber track crawler carrier. Asarco custom-ordered the crawler carrier mounted with a 60-foot Precision Industries spray boom. Spraying a continuous mist of magnesium chloride and water mixture, the crawler carrier mounted boom is being used for dust control that results from high heat and wind at the tailings storage facilities of its Mission Complex in Arizona.

The Terramac® RT9 has proven to be a superior choice for Asarco. While mine roads are typically kept damp by spraying them with water trucks, the heavy, wheeled trucks become bogged down or get stuck completely in the loose and wet ground conditions at the tailings storage areas. The low ground pressure (5.1 PSI) of the Terramac® RT9 makes it ideal for such conditions and Asarco saw it as an alternative to using wheeled vehicles or contracting spray planes for dust control near the tailings ponds.

Mounted to the RT9, the 60-foot Precision Industries spray boom has a stable, sure-footed platform to work from. The ability to equip the RT9 with a 1,600-gallon tank allows the mine to cut the frequency of refills and corresponding downtime by half.

Spray is set to follow a specific flow rate guided by a GPS unit in a precise coverage pattern. Asarco adds magnesium chloride to the water to keep tailings surface moist for a longer periods of time. This means the mine can spray less often while still achieving the same level of dust control.

The 60-foot spray boom is primarily used in mining applications but can also be used in other industries where it is necessary to keep ground conditions moist.
