Header Tanks and Booster Pumps for Gold-Mine Solar Pumps in Mali
Introduction
Solar flow is strongest at noon and weakest at dawn, but a gold mine needs steady process water around the clock—so a header tank and booster step in. This article covers header tanks and booster pumps for gold-mine solar pumps, using Mali’s goldfields—the Sadiola and Morila corridors—as the worked example, written by the solar-pumping specialists at KINBO. The tank banks midday solar so the pump and a small booster deliver constant pressure after dark, the hydraulic partner to our pipe-and-fittings guide.

Why a Header Tank and Booster Matter
- Buffer the sun—the tank stores noon surplus so the duty runs when solar is gone, smoothing the sizing.
- Steady pressure—a small booster on the tank gives constant head to leaching or dewatering, independent of sun.
- Protect the pump—the controller sees a stable load, helped by our pipe-and-fittings guide.
- Cut battery need—a tank is cheaper than cells for overnight buffering, per our TCO guide.
Mali Goldfield Conditions
Mali’s hot, grid-poor gold corridors around Sadiola and Morila need water long after sunset, and diesel is expensive—so a solar-plus-tank buffer is the economical answer. Our dust-and-heat guide and sizing guide frame the duties; here the prize is round-the-clock water from a daytime-only source.
Sizing and Installing, Step-by-Step
- Compute the buffer—from the sizing, size the tank to cover non-solar hours at the duty flow.
- Pick the booster—a small AC or DC pump on the tank delivers constant pressure overnight.
- Route the hydraulics—our pipe-and-fittings guide sizes mains and prevents water-hammer at the booster start.
- Tune the controller—the controller fills by day and the booster tops up by level, not by sun.
- Maintain it—our maintenance guide covers tank cleaning and booster service.
- Verify yield—check overnight delivery against the duty to confirm the buffer holds.
With vs Without a Header Tank
| Aspect | With header tank | Without |
|---|---|---|
| Overnight flow | Yes, steady | Stops at dusk |
| Pressure | Constant via booster | Sun-dependent |
| Cost | Tank beats batteries | Needs storage |
For the cost view, our TCO guide compares tank buffering against battery backup.
Frequently Asked Questions
How big should the tank be?
Big enough to cover the non-solar hours at duty flow from the sizing—usually a few hours of storage, not days.
Do I still need a booster?
For constant pressure after dark, yes—a small pump on the tank does what gravity alone cannot.
Does the tank replace batteries?
For overnight water buffering, largely yes—cheaper than cells, per our TCO guide; keep batteries only for controls.
