Challenge

Effective dust suppression is becoming mandatory as numerous health and environmental concerns associated with excessive airborne particulate matter are raised during mining works. Dust harms the environment, compromises human health, negatively affects communities and reduces overall business productivity. Traditional methods for dust suppression usually require a high amount of water, utilizing 5-9 water trucks per day.

Solution

MetaFLO first applied 3.0% of the DusTech biopolymer, diluted directly in a water truck and applied to the site, with a gold mining tailings soil characterization. DusTech’s application promoted greater agglutination between soil particles, significantly reducing dust suspended in the air. It created a layer on the surface of the soil that reduced the release of fine particles into the air through a clumping process. A second application was carried out after 17 hours, using a 2.0% dosage.

Outcome

✓ COST SAVINGS

Using DusTech for dust suppression over traditional methods cut fuel consumption, emissions of polluting gases, labor and machinery costs by 50%

✓ WATER SAVINGS

Water consumption was decreased by 50%, saving 180,000 liters of water per day and reducing the need for additional surface moistening.

✓ ROAD QUALITY

With DusTech, soil agglutination was improved, and road safety was enhanced—with greater visibility for traffic and improved air quality for employees, the environment and nearby communities.
