The safest way for mines around the globe for Tailings Management

How do you reduce the impact of your tailings, improving the environmental safety and preventing tailings dam disasters?

Industry standards on tailings management have developed over the years, but environmental damage from dam failures still present a danger.

Over the past 40 years, ore grades have declined on average by half for many minerals, effectively doubling the volume of mine waste tailings generated for each unit of mineral produced. Current trends suggest an additional 2-10 fold increase in the extraction and use of most minerals by 2060.

These trends are not sustainable.

Tailings have meaningful community impacts. Safety is a big part of this of course, but engagement needs go beyond safety, given that dams will be a long-term artefact in the area long after the useful life of the mine.

The tailings management facilities require significant changes to find a long-term solution for storing tailings.

There are several filtration options for dewatering tailings after thickening, but the most effective one is the use of filter presses due to the lower capital cost and the large volume of residue being processed.

Sefar is a leader in the design, production and sales of chamber and membrane cloths for filter press machines, also called horizontal, mix pack or vertical plate pressure filters.

We provide solutions for all types of filter presses used in process industries. Our solutions are based on fabrics specifically developed to meet the needs of our customers.

Sefar customized fabrics, specifically developed for the most commonly used filters used in Tailings Dewatering, allow companies to achieve improvements in production yields as well as a reduction of their operational costs.

Thanks to its strong experience in many applications, we have developed a wide range of products to ensure:

• High Filtration capacity
• Reduction of cake moisture
• Excellent cake release
• Best chemical and mechanical stability
• Easy installation
• Extended, long service life

We are also able to propose solutions to suit with the various filter press plate designs: ready-made and specially designed cloths (single, double or overhang), which match the plates perfectly, and offering options such as:

• Metal or ultrasonically welded synthetic Eyelets, with Ultrasonically welded eyelets being resistant to chemical degradation and corrosion
• Different types of barrels and rubbernecks, designed to increase service life resisting chemical or abrasive environments
• Edge sealing through application of coatings or fabric reinforcement to prevent leakage
• Support or backing cloth to increase drainage and lifetime of the filter cloths
