Manganese is a crucial element in the production of ferroalloys and steel. The process of extracting manganese from ores and slags faces numerous technological and environmental challenges, including high energy consumption and metal losses. This paper examines the main methods of manganese...

In this work, the optimal conditions for the extraction of manganese from manganese-containing slags by sulfuric acid leaching were studied. Studies have shown that adding iron powder and iron sulfate to the reaction mixture increases manganese extraction from 45% to 52%, making the process more...

This article presents the results of studies to determine the influence of the amount of modifiers on the physical and mechanical properties of hard alloy samples based on tungstencobalt carbide. Ultrafine nanopowders of titanium carbide and tungsten carbide were chosen as modifiers. The influence...

The article presents the results of research on the production of nanopowders by synthesizing tungsten carbide powders obtained from waste tungsten carbide-cobalt hard alloy in countercurrent filtration mode. The conducted scientific and practical studies show that with an increase in the amount of...
