Reagent Dosing and Chemical Feed Pumps for Gold Mines in Uganda
Introduction
Dosing reagents precisely is both a recovery issue and a safety issue. This article covers reagent dosing and chemical feed pumps for gold mines, using Uganda’s Mubende and Buhweju gold belts as the worked example, written by the solar-pumping specialists at KINBO. Solar-driven metering pumps deliver cyanide, flotation reagents and flocculants at a controlled rate—protecting both the process and the people—and they run where the grid does not reach. This is the dosing companion to our chemical-duty guide.

Why Dosing Matters
- Recovery depends on rate—too little reagent loses gold; too much wastes chemical and complicates tailings.
- Safety demands control—cyanide and acids must be metered, not dumped; overfeed is a hazard.
- Solar suits remote sites—a small PV array runs the metering pump where no grid exists, per our sizing.
- Materials must match—our chemical-duty guide covers compatibility; the dosing pump is the precise front end.
Uganda Site Conditions
Uganda’s gold—the Mubende and Buhweju belts, plus the Kigezi region—is largely artisanal and small-scale, often off-grid and drawing from sediment-laden water. Our dewatering guide, slurry guide and leach guide frame the duties; here the gap is controlled, safe reagent addition at sites that lack reliable power.
Dosing Design, Step-by-Step
- Profile the reagent—list chemistry, concentration, daily volume and required rate from the process design.
- Pick the metering pump—diaphragm or peristaltic, with chemical-compatible wetted parts, sized to the rate with turndown for variation.
- Drive it on solar—a small PV plus controller runs the pump; use a VFD or stroke control for precise rate.
- Filter the feed—strain the reagent so the dosing pump is not clogged by solids.
- Control and log—our remote-monitoring records rate and alarms so over- or under-feed is caught.
- Commission safely—our installation guide covers isolation and containment at handover.
Good vs Poor Dosing
| Aspect | Good dosing | Poor dosing |
|---|---|---|
| Rate | Metered, logged | Manual, guessed |
| Safety | Contained, controlled | Open, hazardous |
| Result | Recovery, safe | Loss, risk |
For the wider chemical duty, our chemical-duty guide covers the pump materials alongside dosing.
Frequently Asked Questions
Can a solar pump dose cyanide safely?
Yes—a chemical-compatible metering pump with contained, logged feed controls the rate precisely; we specify materials per our chemical-duty guide.
What type of metering pump is best?
Diaphragm or peristaltic with compatible wetted parts and turndown; the choice follows the reagent and rate from the process design.
Does it need the grid?
No—a small PV array runs the dosing pump off-grid, which suits Uganda’s remote Mubende and Buhweju sites.
How do I start a dosing solar pump project in Uganda?
Share your reagent profile and rate, and we specify a solar-driven metering pump with safe containment—our installation guide covers commissioning.
