Hydrocyclone Feed Water: Solar Pumps for Sierra Leone Gold Mines
Introduction
Classification is the gatekeeper of recovery, and the hydrocyclone feed must arrive at a constant pressure to cut the ore correctly. This article covers hydrocyclone feed water with solar pumps for Sierra Leone gold mines, using the country’s alluvial and hard-rock operations as the worked example, written by the solar-pumping specialists at KINBO. A staged solar pump keeps the cyclone manifold fed, the classification twin of our controller work.

Why Cyclone Feed Pressure Matters
- Feed the manifold—a steady flow from the pump keeps every cyclone at design head.
- Cut the ore—correct pressure splits fines from coarse, so our cleaning-robot guide reminds you the panels must stay clean to hold that pressure.
- Protect recovery—our efficiency-audit guide shows pressure swings send gold to the wrong stream.
- Plan spares—our maintenance guide keeps the feed on line, under our O&M SLA guide.
Sierra Leone Site Conditions
Sierra Leone’s rainy season floods many alluvial sites, while the dry season turns rivers to trickles, so cyclone feed must cope with both. Our dust-and-heat guide and sizing guide frame the duties; here the prize is a pump that holds cyclone pressure instead of stalling when the source drops.
Sizing the Cyclone Feed Pump
- Read the bank—from the sizing, set the feed pressure and volume for your cyclone battery.
- Buffer the swing—a small tank smooths solar variation before the pump lifts to the manifold.
- 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 classification steady.
Constant vs Cycling Pressure
| Aspect | Constant pressure | Cycling pressure |
|---|---|---|
| Cut point | Stable split | Misclassified ore |
| Fine gold | To correct stream | Lost to tails |
| Result | Better recovery | Wasted grind |
For the cost case, our TCO guide weighs control cost against recovered fines.
Frequently Asked Questions
Why does the cyclone need constant pressure?
Cyclones cut on pressure; swings move the cut point and send gold to tails, so the controller holds the rate.
Does the dry season break the feed?
No—a buffered tank and the pump ride through low source, per our efficiency-audit guide.
How do I confirm pressure?
Pressure logging in monitoring shows the head held, under our O&M SLA guide.
How do I start a Sierra Leone cyclone feed?
Share your cyclone bank duty and we size a buffered, controlled solar pump feed.
