Dry stacking solutions

NewPaakkola’s advanced Dry Stack Tailings (DST) solutions provide a safe, sustainable, and space-efficient way to manage tailings, reducing land use, environmental impact, and improving water management.

Sustainable Land Use

Dry stacking allows tailings to be stored more densely, significantly reducing the land area required compared to traditional tailing ponds. By enabling phased coverage of active stacking areas, the overall open area is minimized, reducing the financial burden of environmental bonds. Dry-stacked tailings are also easier to landscape and blend into the natural surroundings, making land restoration smoother and more effective once mining ends.

Water Management with Conveyor-Based Dry Stacking

Unlike wet stacking, which requires large amounts of water for tailings transport, dry stacking removes water from tailings at the processing plant itself. This enables a nearly closed-loop water system, as the separated water can be recycled back into the mine’s production processes. Overland conveyors and Bridge Stacker solutions by NewPaakkola make dry stacking possible, lowering water usage and reducing water treatment costs.

Minimized Risk and Increased Safety

Dry stacking eliminates the need for large dams, thereby removing the risk of dam failure and subsequent environmental hazards. Without long-term water storage issues, mines can operate with greater safety assurances. NewPaakkola’s dry stacking systems ensure secure and stable tailings storage, supporting environmentally responsible mining practices.

  • Removes the need for large water dams, reducing potential environmental hazards.
  • No long-term water storage issues, ensuring safer mining operations.
  • Provides secure, stable storage with minimal environmental impact.
  • Aligns with sustainable and eco-friendly practices in tailings management.

Sustainable and Cost-Effective Tailing Dry Stacking Solutions

Dry stacking requires less land and fewer resources to manage than traditional methods. NewPaakkola’s conveyor solutions streamline the process, reduce operational costs, and allow mining companies to meet both economic and ecological goals. This innovative approach to tailings management aligns with the global shift towards sustainable mining practices.

Frequently asked about dry stacking

  • How does dry stacking benefit the environment and mining operations?

    Dry stacking offers a range of environmental and operational advantages, making it a sustainable choice for tailings management. By storing tailings in a compact, stable formation, dry stacking significantly reduces the land footprint required, eliminating the need for expansive water ponds or dams. This not only frees up land but also minimizes environmental risks, such as dam failures and hazardous substance leakage, that can arise with traditional wet stacking methods.

    Additionally, dry stacking supports efficient water management by separating water from tailings at the processing stage. This closed-loop system allows water to be recycled directly back into mining operations, conserving water resources and lowering water treatment costs.

  • How does dry stacking help with water conservation?

    Dry stacking involves removing water from tailings at the plant, which enables a closed-loop water system. This significantly reduces the need for fresh water and cuts water treatment costs.

  • Which NewPaakkola solutions support dry stacking?

    Overland Conveyors

    These long-distance conveyors transport tailings across large areas, reducing or eliminating the need for heavy trucks. By continuously moving dry tailings to designated stacking locations, they help lower fuel consumption, minimize dust emissions, and support consistent material flow, optimizing site safety and sustainability.

    Bridge Stacker Systems

    Bridge stackers are designed to place tailings in precise layers, maximizing stacking density and efficiently using available land. They provide controlled, consistent placement of tailings, enabling compact storage while preventing material instability. This controlled stacking method supports safer land use and facilitates easier land reclamation after mining operations end.
