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