Producing more than 6 million tonnes of iron ore annually, the protection of stockpiled fuel stores (coal fines) used for powering large processing facilities is paramount. Pulverised coal fuel is highly vulnerable to wind loss into the atmosphere. Several Arrium operations are at locations where 9-12% of days annually are considered ‘high wind’. The volume of coal dust loss to atmosphere can be heavy indeed.
Approximately 2 years ago, Arrium Mines instituted an all new stockpile protection program using our MINE-CAP product. Using existing water cart spray cannon equipment, simple regimes are applied during peak wind season (July – September). Results have been immediate, with a crust layer of varying depths established, depending on the seasonal need. Arrium mines have calculated a net gain of 66% by using our product, compared with leaving the stockpiles untreated.
