Filter Press Feed Water: Solar Pumps for Eritrea Gold Plants
Introduction
Dry-stack tailings are now the safe default for arid goldfields, and the filter press that makes the cake needs a steady high-pressure feed. This article covers filter press feed water with solar pumps for Eritrea gold plants, using the country’s Bisha, Zara and Koka operations as the worked example, written by the solar-pumping specialists at KINBO. A robust solar pump holds the press feed, the dewatering twin of our controller work.

Why Filter Press Feed Matters
- Feed the press—a steady high-pressure flow from the pump packs the cake instead of starving the chamber.
- Dry the tailings—our thickener-underflow guide feeds the press a dense feed, so solar makes the dry stack possible.
- Protect recovery—our efficiency-audit guide shows pressure swings drop cake solids and waste water.
- Plan spares—our maintenance guide keeps the feed on line, under our O&M SLA guide.
Eritrea Site Conditions
Eritrea’s coastal heat and scarce water make dry-stack the only sane tailings path, so the press must run on solar through long hot days. Our dust-and-heat guide and sizing guide frame the duties; here the prize is a pump that holds press pressure instead of sagging when the sun dips.
Sizing the Feed Pump
- Read the press—from the sizing, set the feed pressure and volume for your chamber count.
- Buffer the swing—a small tank smooths solar variation before the pump lifts to the press.
- Control the flow—the controller trims output to the duty, not the sun.
- Watch pressure—monitoring tracks feed against plan, per our efficiency-audit guide.
- Service it—our maintenance guide and O&M SLA guide keep the cake dry.
Constant vs Cycling Feed
| Aspect | Constant feed | Cycling feed |
|---|---|---|
| Cake solids | Dry, stackable | Wet, unstable |
| Water use | Minimised | Wasted |
| Result | Safe dry stack | Pond risk |
For the cost case, our TCO guide weighs control cost against water and pond savings.
Frequently Asked Questions
Why does the press need constant pressure?
The chamber packs only at design pressure; dips leave a wet cake, so the controller holds the rate.
Does solar cope with Eritrea’s heat?
Yes—our dust-and-heat guide specifies sealed bearings and cooling for the coast and highlands.
How do I confirm the feed?
Pressure logging in monitoring shows the rate held, under our O&M SLA guide.
How do I start an Eritrea filter-press feed?
Share your press duty and we size a buffered, controlled solar pump feed that keeps the cake dry.
