We present the articles of the third issue of scientific journal "Mining Science and Technology” (Russia) for 2024:
A systematic approach to evaluating environmental safety in metro operations, based on modelling the development of defects in tunnel structures under the influence of hydrogeological factors, will help organize existing information on potential accidents and develop monitoring methods and measures to minimize risks that compromise the environmental sustainability of underground transport infrastructure.

Can we extract gold from old mining waste? New research reveals potential
A new study of tailings from Tanzania's Golden Pride Project proves that even low-grade ores (just 0.72 g/t Au) can become profitable thanks to modern technology! Scientists analyzed 1.4 million tons of old waste deposits — long considered worthless — and found they could now be economically viable to process.
Key findings:
✔️ Average gold content: 0.72 g/t, with 74% of the gold concentrated in the fine –75 µm fraction after grinding.
✔️ Dominant minerals: quartz, muscovite, and kaolinite—typical of gold-quartz ore types.
✔️ Minimal harmful impurities (copper <0.05%, sulfur <0.5%), making extraction easier.
How can it be processed?
🔹 Heap leaching — the most cost-effective method for such ores. Similar deposits (e.g., Russia's Mayskoe) achieve 70–80% gold recovery.
🔹 For finer fractions, carbon-in-pulp (CIP) with grinding and classification works best.
Why does this matter now?
With rising gold prices and advancing tech, yesterday’s waste could become tomorrow’s gold source — boosting profits while reducing environmental impact.
