SNF MINING offers a full line of polymer products and equipment to suit the varied needs within the mining industry. The following as some of the markets served by SNF in mining applications:
- Canadian oil sands
SNF, the largest manufacturer of polyacrylamide polymers has been committed to delivering cost-effective, high performance products and systems to the Canadian Oil Sands since 2002. SNF is dedicated to delivering class-leading chemistries for non-conventional crude production in the Canadian Oil Sands.
We understand the critical issues facing today’s tailings management. SNF has provided consultation and servicing throughout the CAPEX and OPEX stages of tailings management including:
- Development of mechanical, operational, and chemical management strategies to help maximize efficiencies from the ground up
- Implementation of solutions to enhance productivity and maximize environmental sustainability
Being the world leader in water-soluble polymers, SNF experts help operators solve problems unique to Oil Sands applications. Our water and process expertise is inherently beneficial due to the continuous treatment required for the reuse and recycle of water needed for separation.
Tailings are made up of natural materials including water, fine silts, residual bitumen, salts, and soluble organic compounds. They also include solvents that are added to bitumen during the separation process.
- Bitumen is derived from the Oil Sands deposits by open-pit mining and water-based extraction techniques
- Recovered bitumen is upgraded into marketable low-sulphur synthetic crude oil (SCO)
Tailings management seeks to improve the speed and efficiency with which tailings, including MFT (mature fine tailings) can be settled, consolidated, and used for reclamation purposes – all while reducing the need for larger and larger land areas for ponds.
SNF Energy Services personnel work with our customers to help them improve their tailings management operations, and to comply with current regulatory directives.

SNF provides customers with sound solutions for the remediation and reclamation of contaminated and non-contaminated sediments. This can take place with any waterway, or any municipal or industrial lagoon.
With an extensive range of polymers, preparation and dosing equipment manufactured in-house, and a well-seasoned team of application specialists, SNF Environmental offers a comprehensive range of unique capabilities and resources that no other polymer supplier in the industry can provide. Regardless of the industry or duration of the project, SNF Environmental can design a program that will best suit your needs.
SNF polymers are sold and marketed extensively in municipal and industrial wastewater treatment applications worldwide. Many of these same SNF polymers are also used by dredging contractors for enhanced solids-liquids separation of dredged sediments in order to reduce sludge volumes that must be reclaimed or disposed of. In doing so, settling, thickening, and dewatering times can be significantly reduced versus using large land areas for ponds.
Settling/Thickening of dredged sediments to obtain a clear overflow by injecting polymer:
- Directly into hopper dredges – to enhance settling rate of sediment and clarify overflow water for discharge
- Prior to settlement ponds – improved settling rate of sediment and solids capture mean less land and fewer ponds necessary, with cleaner overflow water for reuse or discharge
Dewatering of dredged or pre-thickened dredged sediments in order to produce friable cake solids capable of being reclaimed or disposed of. Some of the common dewatering methods used in dewatering dredge sediments with the aid of SNF polymers, equipment, and service are:
- Geotextile tubes
- Belt filter presses
- Plate and frame presses
- Screw presses
SNF’s proposal is a change from the traditional lagooning process for dredged sediments from port construction or waterways dredging projects. Typically after many years of natural drying in upland or nearshore containment ponds or lagoons, the resulting dried sediment is heterogeneous. However, with the use of SNF polymers injected prior to settling/thickening within a containment pond or lagoon, homogenous flocs comprised of sand and fine particles leave valuable land or dewatered solids after only 6 months of drying time. Our process means that less acreage is required for settling areas, and land can be re-used after only 6 months. It is a cost-effective alternative, as there is less capital investment needed, and our process is less expensive overall to operate than conventional sediment settling and disposal on a total cost basis.
In the case of contaminated sediments, SNF polymers are able to enhance dewatering of those sediments, resulting in cleaner discharge water and reduced volume of solids that need to be transported and disposed of in an approved hazardous waste landfill.
