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.
