GOLD MINING
Slurry Pumps & Dredging Equipment for Gold Mining
Move gold ore slurry, tailings, and alluvial material without losing production to wear or clogs.
Gold operations pump abrasive ground-ore slurry through leach and recovery circuits, send tailings to storage, dewater pits and shafts, and in alluvial deposits dredge gravel and sand to a recovery plant. EDDY Pump supplies high-solids slurry pumps and dredging systems for each of these duties. The pump moves the material; recovery happens in your plant.
Move the Slurry. Recover Gold in the Plant.
A gold mining slurry pump moves the ore, tailings, or alluvial material between process steps. It does not separate gold from the slurry. Match the pumping arrangement to the feed your recovery plant can accept and the material conditions at the intake.
Watch the EDDY Pump gold mining overview for an introduction to slurry transfer and dredging equipment. Final selection depends on the solids, chemistry, flow, head, and access at your site.

Tailings transfer, pond cleanout, and legacy material reprocessing.
Alluvial & Placer Deposits
Sand, gravel, and mixed material moved to a recovery plant.
Mine Dewatering
Solids-bearing water in pits, sumps, shafts, and underground works.
Gold mines, placer operations, and legacy tailings sites where abrasive solids wear out or clog conventional pumps, or where settled or submerged material has to be reached directly.
FROM ORE TO TAILINGS
Common Gold Mining Applications
01
Ore Slurry Transfer
Move ground-ore slurry from the grinding circuit toward leach or flotation processes.
02
Leach & CIP/CIL Circuits
Review carbon-bearing slurry, pH, leach chemistry, materials, and seals before selection.
03
Tailings Transfer
Move process tailings through a pipeline to the designated storage facility.
04
Tailings Pond Reclamation
Dredge settled or legacy tailings for transfer to a reprocessing circuit.
05
Pit & Shaft Dewatering
Remove solids-bearing water from pits, sumps, shafts, and underground workings.
06
Alluvial & Placer Dredging
Transfer gold-bearing sand and gravel to a recovery plant; separation takes place there.
07
River & Creek Sediment
Remove accumulated sediment near operations within the project’s permitted work area.
08
Pond & Reservoir Desilting
Restore capacity by removing settled material. See the Cresta Reservoir case study below.
09
Legacy Site Remediation
Move sediment and slurry as part of a defined reclamation or remediation plan.
The pump moves material to the next process step. Gold separation, reprocessing economics, and environmental controls depend on the plant and the project. Leach and CIP/CIL duties require application review.
RELATED RESERVOIR DREDGING CASE STUDY
Cresta Reservoir: Sediment Removal in Practice
A 1994 EDDY Pump demonstration at Cresta Reservoir in northern California moved sandy reservoir deposits while monitoring production and water quality. It provides a reference for pond and reservoir desilting alongside mining operations.
This was a reservoir sediment project, not a gold recovery trial. The reported results describe that demonstration and do not guarantee performance for a different slurry, pipeline, or site.

PUMP & DREDGE OPTIONS
Recommended EDDY Pump Equipment for Gold Mining
Start with the source material and the access method. Confirm the duty point, slurry properties, and materials before choosing equipment for the job.
Submersible Slurry Pumps
Best for pits, sumps, shafts, and ponds where the pump can work directly in the slurry.
Self-Priming Slurry Pumps
Best for surface-mounted or mobile dewatering and transfer with the pump kept above the source.
Excavator Pump Attachment
Best for alluvial gravel and compacted tailings where digging, agitating, and pumping happen from one machine.
Autonomous ModDredge / Dredge Sled
Best for tailings ponds and basins that need repeatable dredging coverage.
Cable-Deployed Dredge / Diver-Operated Dredge
Best for deep or confined ponds (crane-placed) and localized underwater work (diver-controlled).
Booster Pumps
Best for long tailings or dredge pipelines and high-TDH systems.
MATERIAL & SITE CONSTRAINTS
Challenges in Gold Mining Slurry Pumping
Ground ore, settled tailings, and alluvial gravel place different demands on a pump. Include the chemistry, carbon content, and site access alongside the solids and duty point.
01
Abrasive Ground Ore
Crushed and ground ore wears impellers, liners, and close clearances quickly.
02
Leach Chemistry and Carbon
High-pH leach solutions and carbon-bearing slurry in CIP/CIL circuits need material, seal, and duty review before any pump is chosen.
03
Settled and Legacy Tailings
Older tailings ponds compact and crust, so the intake often needs agitation before material can be pumped.
04
Alluvial Gravel and Debris
Riverbed and placer material carries cobbles, roots, and mixed solids that can plug restrictive flow paths.
05
Wet, Remote, and Submerged Work
Pits, shafts, creeks, and ponds limit access, and the equipment often has to work below grade or underwater.

This table starts the application review. Final selection depends on the solids, slurry density, chemistry, flow, head, access, and pipeline. Leach and CIP/CIL service requires specific materials and seal review.
APPLICATION PLANNING
Plan the Gold Mining Slurry System
Define the Ore Slurry and Process Circuit
Start with the material at the pump intake. Record whether the duty involves ground ore, carbon-bearing slurry, fresh tailings, or mixed mine water. Provide the normal and maximum particle size, solids concentration by weight, slurry specific gravity, temperature, and target production. These inputs describe the load the pump will carry and help engineering assess the flow path, drive, and expected wear.
For a gold ore slurry pump in a leach or CIP/CIL circuit, include pH, leach chemistry, and carbon presence. High Chrome is a starting direction for abrasion, but chemistry can change the wet-end and seal selection. The pump must suit the actual circuit conditions. Pumping supports material transfer; gold recovery remains the job of the downstream process.
Define the Ore Slurry and Process Circuit
Plan Tailings Transfer and Reclamation
Fresh tailings and an old pond deposit may require different intake arrangements. Describe the depth of material, settling behavior, crust, and any compacted layers. A gold tailings pump needs a reliable supply of material at the inlet. An excavator attachment can combine mechanical agitation and pumping, while a ModDredge or Dredge Sled may suit a pond that needs repeatable coverage.
When reclaiming legacy tailings, confirm where the slurry will go and what the reprocessing circuit can accept. Share the target production, access, liner constraints, and discharge route before selecting a dredging system. The related Cresta Reservoir example shows a historical sediment-removal duty; recovery potential and the economics of your tailings must be evaluated from your own material and plant.

Match Alluvial Dredging to the Deposit
Alluvial and placer deposits can contain sand, gravel, cobbles, roots, and other debris in the same work area. Supply the largest expected solids and describe changes across the deposit. A placer mining dredge pump must reach the material and feed the pipeline without depending on an assumption that every part of the deposit will behave the same way.
Choose the deployment method around bank access, water depth, and the work area. An excavator pump attachment may suit material that needs digging or agitation. A cable-deployed system can reach deep or confined areas with crane access, while a diver-operated dredge suits localized underwater work. Confirm the receiving plant, permitted work limits, and environmental controls before establishing the transfer arrangement.
Choose Pump Access for Pits, Shafts, and Sumps
Mine dewatering with solids is a different duty from pumping clean water. Identify the solids entering the pit or shaft, the range of water levels, and the available installation space. A submersible slurry pump places the intake in the material. A self-priming arrangement keeps the power package above the source and may suit temporary or mobile transfer where the suction conditions permit it.
Include pump deployment and removal in the access plan. Below-grade or underground work needs a practical route for installation and service, as well as a defined discharge destination. State the available power source, operating hours, and site constraints. Select from the actual required flow and head rather than treating pit depth or pipe distance alone as the complete duty.
Size the Full Gold Slurry Pipeline Duty
Give the required slurry flow together with total dynamic head, pipeline length, internal diameter, and vertical rise. If the production target is stated in cubic yards per hour, specify whether it refers to solids or total slurry. Keep the material data with those figures so engineering can review solids concentration and density against the proposed route.
Long tailings or dredge pipelines may need booster pumps when friction and elevation exceed the primary pump duty. Confirm the combined system before committing to a pump arrangement. A high production target by itself does not establish a workable operating point, and a result from another project does not replace a curve review for your slurry and pipeline.
Complete the Project-to-Plant Handoff
Bring the slurry characteristics, source geometry, access plan, duty cycle, and receiving process into one application review. Identify power, temperature, chemistry, liner constraints, and any permit limits that affect deployment or operation. For reclamation or remediation work, define the material destination and the project’s water-handling requirements before the equipment package is finalized.
Use the configuration table below as the first screen, then supply the sizing information with your request. Engineering can assess the primary pump, deployment method, materials, seals, and any booster requirement together. Keep the boundary clear: the pumping system transfers the feed, while the processing plant determines how the gold is separated from that material.

FREQUENTLY ASKED QUESTIONS
Gold Mining Slurry Pump FAQs
Answers about ore slurry, CIP/CIL review, alluvial dredging, tailings reclamation, mine dewatering, and pump sizing.
What Pump Is Used for Gold Ore Slurry?
Heavy-duty slurry pumps move gold ore slurry. The right configuration depends on solids size, slurry density, chemistry, and whether the pump sits in a sump, feeds a tank, or runs a long pipeline.
Can EDDY Pump Be Used in CIP or CIL Circuits?
Only after application review. Carbon-bearing slurry, leach chemistry, and pH affect material and seal choice, and the pump must suit the circuit. EDDY Pump does not assume a fit without the duty details.
Can EDDY Pump Dredge Alluvial Gold Deposits?
Yes. EDDY dredging equipment can move alluvial gravel and sand as slurry from riverbeds, creeks, and ponds to a recovery plant. Separating the gold happens in that plant, and the operator is responsible for permits and environmental controls.
Can EDDY Pump Reclaim Gold-Bearing Tailings?
EDDY Pump can dredge old tailings and pipe them to a reprocessing circuit. Whether reprocessing pays depends on the material and your plant.
What Pump Dewaters a Gold Mine Pit or Shaft That Carries Solids?
A submersible slurry pump handles water with solids directly in a pit, sump, or shaft. Flow, head, solids size, and access decide the size and layout.
How Do I Size a Gold Mining Slurry Pump?
Start with required flow and total dynamic head, then correct for slurry density, solids concentration, particle size, pipe length, elevation, and wear. EDDY Pump reviews these from the sizing checklist above.
