Seawater in the large-scale mining industry: opportunity for new suppressors

Thursday, January 10, 2019

ABCDust statement

The higher copper production expected by the end of this decade, will make the use of seawater by copper mining increase by 230% by 2029 (Cochilco, 2018). This will intensify the use of brines to irrigate roads for dust control, which is an excellent opportunity for advanced additive lines such as ABCDust's DMS® copolymers, which combined and added in minimum quantities obtain suppressions greater than 94% of particulate material MP10-2,5.

The study developed by the Chilean Copper Commission (Cochilco), showed that the demand for seawater in the sector will go from 3.28 m3 / sec in 2018, to 10.82 m2 / sec in 2029, thus reaching 43% of the total water required by that industry in that year. Excellent news for the line of suppressors DMS, which enhances the use of salt water for dust control, stabilization and conservation of roads.

Enhancing the hygroscopicity of seawater

The combination of DMS polymers takes advantage of and complements the salt water hygroscopy, they agglutinate and bind fine particles increasing density, strength and uniformity to the binder, better flexibility and firmness, they conserve optimum moisture, lubricating the friction between particles, and minimizing loss of fines, and reduce the corrosion typical of an intensive salt-saturated treatment. The combined result is a road with excellent preservation conditions, with a 94-98% dust suppression and 80-90% irrigation reduction, saving tanker hours and obtaining a higher productivity of the road network.

In addition, for maintenance of large road networks, our expert team performs a diagnosis to determine the model and protocols of optimal dosing performance to apply and conserve the treatments in a geolocalized manner in each section of the road circuit. For this, multiple variables are integrated into deterioration models and monitoring systems of MP10-2.5; friction, levels of regularity,% fines,% salts and conditions of the road and the environment.
