MINING APPLICATION
Tailings Pipeline & Spigot Isolation
Extend maintenance intervals and ensure environmental protection with valves engineered for high pressure and high solids tailings.
Maximize Mill Uptime With Reliable Tailings Management
Mill waste, or tailings, are abrasive and cause severe wear on piping components as they are collected and delivered to the tailings storage facility (TSF). Tailings applications often see the highest solids content slurry, and highest pipeline volume, and can have a wide range of pressures. Isolation valve performance and life span have a direct impact on mill throughput and operating costs.

Isolation Valve FAQs
What does tailings mean in mining?
“Tailings" refer to the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are the by-products of the extraction processes used in mining to recover metals, minerals, or coal.
What is a spigot in mining?
A spigot refers to a specific outlet used in the distribution of tailings in a tailings storage facility (TSF), such as a tailings dam or a tailings pond. The primary function of a spigot is to discharge the tailings slurry into the designated area in a controlled manner.
Why is valves selection critical for tailings pipelines?
Selecting the appropriate valves for tailings pipelines is critical to ensuring optimal performance, durability, and safety specific to your tailings pipeline system.
What is the importance of isolating and directing the flow of slurry in tailings management?
It ensures that tailings are managed in a controlled, predictable manner, minimizing risks to people, the environment, and infrastructure.
