🔥 We present one of the articles from the new issue of the journal "Mining Science and Technology" (No. 2, 2026)! The Norilsk deposits are one of Russia’s largest mineral resource bases. However, high-grade ore reserves are depleting, and over the next 20 years, production volumes will increase by 30%, while ore value will decline by 35%. How can product quality be maintained? The authors of the article proposed an integrated approach: they updated ore quality management methods for underground mining, classifying them into blending and stabilization methods and segregation and separation methods. Production studies confirmed the existence of significant reserves for effective ore flow management. What does this offer for practice? A technological scheme for an underground quality management system has been developed, including an information and control structure with real-time monitoring of metal content at all stages — from the face to the surface. This allows improving the quality of commercial ore and the stability of its mineral composition. 📖 Read more: Turtygina N.A., Okhrimenko A.V., Glinsky A.V., Ryzhenkov K.A.
