Process Water Recovery and Closed-Loop Systems for Solar Pumps in Gold Mines in Togo
Introduction
In a water-scarce mine, every litre pumped should be used, not lost. This article covers process water recovery and closed-loop systems for gold-mine solar pumps, using Togo’s gold projects—the northern and central greenstone prospects—as the worked example, written by the solar-pumping specialists at KINBO. Closing the loop reclaims tailings and process water so the pump recirculates instead of drawing ever more. This is the water-stewardship companion to our storage-tank guide.

Why Closed-Loop Recovery Matters
- Cut draw—reclaiming tailings and process water shrinks what the pump must lift from source.
- Ease许可—lower intake and discharge help with the permitting and community licence to operate.
- Protect the duty—less source dependence steadies the sizing against droughts.
- Reuse reagent—closed loops keep the chemistry our dosing guide adds in circulation, not lost to bleed-off.
Togo Site Conditions
Togo’s small, water-conscious gold projects face community and regulatory pressure to minimise draw and discharge, so recovery pays twice. Our storage-tank guide, dosing guide and permitting guide frame the duties; here the prize is a loop that recirculates at the northern prospects, so closed-loop recovery earns its keep.
Recovery Design, Step-by-Step
- Map the water—from the sizing, every inflow, process use and discharge across the circuit.
- Set the targets—reclaim percentage and make-up water needed, plus the storage to buffer the loop.
- Clarify and filter—settling and filtration return tailings water clean enough to recirculate without fouling the pump.
- Recirculate—the pump draws from the recovered buffer, not the source, cutting draw.
- Close the chemistry—top up reagent per our dosing guide so the loop stays effective.
- Monitor quality—level and quality sensors feed monitoring to keep the loop balanced.
Closed-Loop vs Once-Through
| Aspect | Closed loop | Once-through |
|---|---|---|
| Source draw | Minimal make-up | Full demand |
| Discharge | Small, controlled | Large |
| Result | Steady, permitted | Drought-exposed |
For the cost view, our TCO guide shows recovery’s saved draw and permit ease beat the treatment cost.
Frequently Asked Questions
Does closed-loop mean no new water?
No—there is always some make-up for evaporation and bleed-off, but far less than once-through, shrinking what the pump draws.
Will recovered water foul the pump?
Not when clarified and filtered first, so the loop returns clean water to the pump intake.
Does recovery help permitting?
Yes—lower draw and discharge ease the permitting and community licence, per our permitting guide.
How do I start a recovery project in Togo?
Share your northern or central circuit’s water map and targets, and we design a closed loop that recirculates recovered water through your pump.
