Paste & Thickened Tailings

A Critical Mining Decision

Tailings disposal is an essential element of mining viability. Today, economic and environmental factors make that decision even more critical, with tailings management often determining the success or failure of a mine.

Creating Optimized Systems

PSI has the specialized knowledge and expertise to design and build optimized systems for paste and thickened tailings disposal. Whether your need is for paste backfill or surface disposal, PSI will provide the perfect combination of products and services, including energy dissipation, high-pressure pumping, cycloning, thickening, materials selection, and specialized construction.

Benefiting from Reduced Water Usage

At PSI, we also understand that the industry is moving toward systems that minimize the amount of water in the tailings stream. We apply our understanding of complex hydraulics and tailings disposal methods to your particular mine layout to identify solutions that will result in longer design lives, reduced failure risk, and increased storage efficiency.
