  • Zinc Ore Online Analyzer

    Lyncis LIBS zinc ore online analyzer is a radiationfree technology used for process optimization in achieving costeffective zinc production. Production of zinc is becoming more and more difficult with growing variations in the chemical composition of raw materials. This leads to lower metals recovery and significantly increases reagents and energy consumption in the production process.
