Dry technologies for processing and enrichment of mineral raw materials - pros and cons!
The use of dry methods of processing and beneficiation of mineral raw materials is one of the promising areas, as this approach to concentrate production is less energy-consuming, less labor-intensive, and economically beneficial. However, this method of enrichment is not always technologically effective. Experimental studies on the experimental studies on preliminary dry separation of Arkachan deposit ores to determine the quality of beneficiation of the separation products are presented in an article in the journal Mining Science and Technology. The results of the study showed, dry beneficiation as applied to the ores of Arkachan deposit is technologically inefficient. Additional laboratory studies of pneumatic separation processes at high degree of ore materials grinding are required. The authors of the study are confident that their methodological approach will be useful for colleagues in substantiating technologies for processing and beneficiation of mineral raw materials.

How to Optimize Ventilation in Mines Using Diesel Equipment?
🔹 Problem: Modern mines utilize high-power diesel equipment, significantly increasing ventilation load. Traditional airflow calculation methods overestimate requirements by 50%, leading to substantial costs.
🔹 Solution: Researchers developed a novel methodology based on field measurements of actual emissions and numerical simulation. This enables precise determination of airflow needed to dilute harmful substances to safe concentrations.
🔹 Key Results:
✅ Reduced ventilation costs through accurate emission accounting
✅ Optimized air distribution in mine workings
✅ 3.5× decrease in CO and NO₂ concentrations with proper ventilation
For more information, see the article:
📌 Senatorov V.A. Determining airflow requirements in mine workings based on field measurements of actual emissions from internal combustion engine equipment. Mining Science and Technology (Russia). 2024;9(1):53-59. https://doi.org/10.17073/2500-0632-2024-01-203
💡 Conclusion: Innovative calculation methods represent a breakthrough in cost efficiency and environmental safety for mining operations!

We present the articles of the second issue of scientific journal "Mining Science and Technology" (Russia) for 2025:
Scientists have proposed a new approach to calculating the optimal width of a dredge front bank, which reduces the cost of placer deposit mining. The study demonstrates that existing methods, focused solely on maximizing dredge productivity, fail to minimize costs when the depth of the placer and overburden thickness increase. The authors developed a methodology for determining the front bank width that accounts not only for dredge performance but also for stripping costs and the extraction of valuable components. The research analyzed the influence of placer parameters (peat thickness, productive layer thickness, front bank width) on economic efficiency, evaluated over 100 process flow sheets for equipment operation, and provided their economic assessment. The results include recommended correction factors for calculating the optimal front bank width, serving as a methodological foundation for designing dredge mining systems.
For details, see the article in Mining Science and Technology:
