Drilling waste BC
Drilling waste in BC in need of solidification at remote mountain top site. Drilling mud produced near slopes estimated at greater than 28⁰ restricting mobility and truck access. Project deadline was constrained by heavy rain prior to mobilization and wildlife migration and fisheries preservation. Thin layers of gravel-like natural soil provided inadequate soil properties for mix-bury-cover site processing.
MetaFLO’s technology offered space savings suitable to the site. Additionally, by applying MetaFLO’s patented high shear solidification process, the difficult residual drill waste could be managed for compliant mix-bury-cover. The challenge of managing the drill waste would otherwise have made the whole drilling operation cost prohibitive.
Project was completed in required timeframe. The expertise of CCI and Talisman crews working with MetaFLO technology produced a solidified material surpassing all regulatory requirements.
Owner: Vale Canada Ltd.
Contractor: Tervita Corp.
Vale owns and operates a mining site in Northern Ontario, Canada. Through their mining and refining activities they produce a sludge waste by-product. The clients were in need of an efficient excavation and transportation solution to get this sludge to their off-site landfill.
End of September 2018 - Mid October 2018
During the bidding process, MetaFLO was engaged to provide an optimal blend and dosage rate to achieve the solids criteria required for excavation and transportation of the sludge. Using analytical data, MetaFLO estimated a dosage rate of 1.1% by weight (based on a high moisture content). Large mixing bins were recommended for increased surface contact and efficiency during the bucket mixing process. No sample was available at this time.
Tervita Corporation utilized MetaFLO reagent to solidify approximately 4,000 m3 of sludge. Two 35m3 bins were staged on site and were loaded with a composite of “heavier” and “lighter” sludges. The originally estimated dosage rate was accurate as actual treatment averaged approximately 30lbs of MetaFLO MF006 reagent per m3 of sludge. All material was safely shipped to Vale’s off-site landfill. The job was completed on time.
