XRF for Better Plant Metallurgy Control

XRF for Better Plant Metallurgy Control

An un-monitored (un-assayed) tailing from a vibrating screen was exiting the system.  Operators would eyeball the Zinc content from a handcut while true assays were only provided late the next day as part of the metallurgical material balance.

Here I show 4 videos of the new step by step solution we implemented.  It used a pizza oven as a drier, a small jaw crusher for sample preparation and Olympus XRF for live assays.  This has allowed for an immediate stabilization and >30% or so reduction of zinc metal loses.

Note the resulting assay of around 800-900 ppm Zn and 5000 ppm Fe = 0.09%Zn and 0.5% Fe.
