Uses of XRF in Nickel Mining and Exploration
Nickel is a two-deposit-type story, and the XRF application is genuinely different depending on which one you're working on.
Let's talk through both.
Nickel Sulfide Deposits
Sulfide deposits account for roughly 40% of global nickel production and include some of the highest-grade nickel operations in the world. They form in settings where nickel, copper, cobalt, and platinum group elements co-deposit in sulfide phases. Economic grades typically run 0.5 to 3% Nickel, concentrations that sit comfortably within XRF detection capability in core and rock samples.
For nickel sulfide exploration, XRF is measuring the commodity element directly. You scan core as it comes out of the hole and you know where the high-grade zones are in real time. No waiting on the lab to tell you what you're looking at.
The associated element suite is where it gets even more useful.
Copper, cobalt, chromium, iron, and magnesium are all XRF-detectable alongside nickel. When you're in a mafic-ultramafic sequence and you're seeing elevated nickel, copper, and cobalt together in your XRF readings, that's a geochemical signature worth paying attention to. The instrument is essentially reading the fertility indicators of the magmatic sulfide system while you're still at the core tray.
Nickel Laterite Deposits
Laterites are a different animal entirely.
They form from tropical weathering of ultramafic rocks, and the nickel concentrates through the weathered profile. Limonite at the top, saprolite in the middle, fresh rock at the base. The grade distribution through that profile varies, and understanding it quickly is exactly what XRF is good at.
Field XRF characterizes the laterite profile in real time. Nickel alongside iron, magnesium, cobalt, and silica at every sample point. You're building a picture of grade distribution through the profile as you go, not weeks after the field program wraps up.
Cobalt is a critical co-product at many laterite operations, and it varies significantly through the profile. XRF cobalt measurement alongside nickel means you're capturing both at every point simultaneously, the kind of spatial co-product data that takes much longer to build from laboratory-only programs.
One thing to watch for in laterite processing is chromium. Elevated chromite in ore drives up processing costs, and XRF flags high-chromite zones during both exploration and grade control. It's the kind of real-time quality control flag that pays for itself when you're routing ore to a hydrometallurgical plant with tight chromium tolerances.
Grade Control for Both Deposit Types
Whether you're running a sulfide operation or a laterite mine, XRF at the blast hole and pit face puts grade data in the hands of the people making mining decisions in real time. Ore-waste boundaries stop being visual approximations and start being chemistry-based calls, and selective mining of high-grade zones becomes practical when you have grade at every hole rather than interpolating from sparse laboratory samples.
The sulfide versus laterite distinction matters for understanding which elements to focus on and which modes to run.
But the core value of XRF is the same for both. Faster decisions, better targeted drilling, and grade control based on chemistry rather than guesswork.
Bring real-time nickel grade data to your exploration program or laterite operation.
