Canadian Submersible Slurry pump Applications
Tailings ponds are a critical component of modern mining operations across Canada. These large containment areas hold slurry waste produced during mineral processing and must be carefully managed to maintain environmental safety, operational efficiency, and regulatory compliance.
Canada’s mining industry produces millions of tonnes of tailings each year from mineral processing operations. Tailings ponds are widely used across the country to manage these materials.
All require reliable slurry pumping systems capable of operating continuously in harsh conditions.
Goodwin Submersible slurry pumps are commonly used for:
Tailings pond dredging
Tailings transfer pumping
Thickener underflow pumping
Lagoon cleaning
Settlement pond maintenance
Process water recovery
Mining operations in provinces such as:
Alberta – oil sands tailings
Ontario – nickel and gold mining
Quebec – gold and iron ore
British Columbia – copper and molybdenum
Saskatchewan – potash mining
A tailings pond slurry pump must operate reliably in extremely abrasive conditions while handling high solids content, dense slurry mixtures, and fluctuating pumping depths.
Goodwin pumps are especially suited to sump pumping, where they will easily outperform cantilever-type pumps.
Submersible slurry pumps from Goodwin International Ltd are engineered specifically for demanding mining environments, allowing operators to efficiently pump and manage tailings without the limitations associated with traditional suction-based pumping systems.
Because the pump operates fully submerged, it eliminates suction lift limitations and provides reliable pumping performance even in deep tailings ponds or remote mining operations.
Tailings slurry is significantly more challenging to pump than standard water or wastewater due to several operational factors:
High solids concentration
Abrasive mineral particles
Large settlement zones within ponds
Changing pumping depths
Remote mining locations
Traditional centrifugal pumps installed on the surface often struggle with suction limitations, air entrainment, and reduced efficiency when handling dense slurries. A submersible tailings pond slurry pump eliminates these challenges by positioning the pump directly within the slurry source.
Heavy-duty impellers and wear components allow efficient pumping of slurries containing high concentrations of solids.
The pump is positioned directly in the slurry, removing suction head limitations and improving reliability.
Submersible pumps eliminate the need for complex suction pipework, priming systems, and pump houses.
Wear components are designed to handle abrasive materials commonly found in mining tailings.
Pumps can operate effectively at significant depths, making them ideal for large tailings facilities.
Goodwin pumps are engineered for demanding mining environments where reliability is essential.
Key design features include:
Heavy-duty high-chrome wear components
Large open impellers designed for solids handling
Fully submersible hydraulic motor design
High torque capability for dense slurries
Capability to pump slurries with high specific gravity
Robust construction for continuous mining duty
These features allow Goodwin pumps to handle abrasive tailings materials with reduced wear and improved operational uptime.
Over time, sediment accumulation in tailings ponds can reduce available storage capacity and impact site operations.
Submersible slurry pumps can be used for:
Removing settled tailings deposits
Reclaiming valuable minerals
Maintaining pond capacity
Cleaning settlement lagoons
When mounted to excavators or floating platforms, submersible pumps can also be used for mechanical dredging of tailings ponds.
Selecting the correct tailings pond slurry pump requires understanding the operating conditions of the mining site.

Effective tailings management is essential for safe and efficient mining operations. Selecting the correct tailings slurry pump ensures reliable slurry handling while minimising operational downtime and maintenance requirements. Submersible slurry pumps provide a robust solution for pumping abrasive mining tailings in challenging environments commonly found across Canada’s mining sector.
Tailings slurry can contain high concentrations of abrasive mineral particles, which cause wear on pumps. Slurry density and particle size also vary, requiring robust pump designs capable of handling changing conditions.
