Solar Pump Systems for Gold Mine Laboratory and Assay Water
Introduction
A gold mine’s laboratory is where the ore is proven—fire assays, atomic absorption, digestion and gravimetric work all depend on a reliable supply of clean water. At a remote African site that water is usually produced on site, and a diesel-driven purification or delivery pump is a fragile, fuel-hungry link in a quality-control chain that cannot afford variability. A solar pump delivers the lab’s raw and make-up water off-grid, quietly and consistently. This article covers solar pump systems for gold-mine laboratory and assay water, from specialists at KINBO.

Where the Lab Uses Water
- Sample preparation—washing, screening and pulping of samples before assay.
- Digestion and analysis—acids are made up with water; AAS and ICP need consistent-quality make-up.
- Fire assay—cupellation and flux work need clean process water and cooling.
- General lab—glassware, safety showers, and the small but constant draw of a working laboratory.
The lab’s water is a quality input, not just a utility—so supply stability matters as much as the energy saving. Pair this with our camp supply and treatment guides.
Selecting the Lab Water Pump
- Clean-water centrifugal or booster—moves raw water from the source to the lab’s pre-treatment (filtration / reverse osmosis) skid.
- Low-flow make-up—lab draw is modest, so a small, efficient pump with a buffer serves it; our micro-dosing guide covers small precise duties.
- Materials—clean, often demineralised after treatment; standard wet-ends are fine before purification, corrosion-resistant after.
- Control—a VFD-style solar controller holds pressure to the lab skid as the array output varies.
Solar Drive and Buffer
- Small array—lab demand is low, so the PV is small; size with ~20% headroom and a battery to ride through cloud.
- Buffer tank—an elevated tank between source and lab means the purification skid never starves, even at night.
- Monitoring—a simple level or flow sensor (our remote-operations guide) confirms supply so a QC issue is never traced to a dry pump.
Solar vs Diesel Lab Supply
| Factor | Diesel Lab Supply | Solar Lab Supply |
|---|---|---|
| Energy cost | Per run-hour | Zero after install |
| Supply stability | Fuel-dependent | Buffer holds steady |
| Footprint | Gen + fuel at site | Small panel + battery |
| Best fit | Grid-connected labs | Remote off-grid labs |
Because lab water quality underpins every grade estimate, a stable solar supply is a quality-assurance asset, not just a cost cut.
Frequently Asked Questions
Can solar run the purification skid too?
The pump delivers raw make-up water to the lab’s own filtration/RO skid; solar handles the delivery, while the lab’s existing purification does the polishing. We size the pump to the skid’s input demand.
What if the lab runs at night?
A small battery sized to overnight draw keeps the buffer tank topped, so assays and digestions never wait for sun.
Is the water clean enough for assay?
The pump supplies source water to your pre-treatment; specify the treatment you already use. Solar simply delivers it reliably off-grid.
How big an array does a lab need?
Lab draw is low, so the array is small—typically a fraction of a process-duty pump. We size from your make-up flow and the skid’s pressure requirement.
