From the first feed to concentrate, every stage depends on machinery, measurements and connected systems. Explore the plant and discover where we can support your operation.
The whole mine, working
From the ground to concentrate
Follow ore from the pit and shaft through crushing, conveying, grinding, flotation and dewatering. Select any part to look inside, or play the tour. The analysers mark typical points where XRF measures the material as it moves. A representative mine, not a site design.
The connected mine
Select any part, or drag and scroll to look closer.
Process breakdown
One plant, many systems
A representative copper sulphide concentrator, not a site design. The concentrator includes several circuits; flotation is one of them. Motion is illustrative. Equipment ratings and operating conditions vary.

Receive & crush
01 / Inside the process
Ore receiving
Ore enters the processing plant through a receiving and feed arrangement. A hopper provides an interface between arriving material and the feeder that controls delivery to the next stage. This is a representative surface-plant view, not a mine layout.
- What arrives
- Mined copper-bearing ore
- What leaves
- A regulated feed toward primary crushing

Analysis points
XRF at the analysis points
What XRF measures
X-ray fluorescence excites the atoms in the material with X-rays. Each element answers with X-rays of its own characteristic energy, so the analyser can tell copper from iron or cobalt and estimate how much of each is present.
Why measure online
Laboratory results arrive hours after the sample was taken. An analyser over a belt or on a slurry stream reports every few minutes, so operators and control loops can react while the material is still in the circuit.
Sampling and calibration
An online analyser is only as good as its calibration. It is calibrated against laboratory assays of representative samples, checked regularly, and recalibrated when the ore changes. Every result carries a timestamp and a quality flag, and a stopped belt or a lost signal is never reported as zero grade.
Peter Kabamba, Quantic Engineering Limited's Engineer/MD, is the lead XRF Engineer for Mundala Corporation Limited. Equipment suitability and each company's responsibilities are agreed for the specific application.
XRF, sampling and analysisConcentrate is part of the copper story
This explorer focuses on the sulphide concentrator, concentrate dispatch and tailings/water interfaces. It does not depict a complete smelter, refinery or leach circuit. Subsequent copper recovery follows the selected ore and process route.
