The increase in the integrated use of oxidized and mixed copper ores largely depends on creation a technology that allows not only to extract copper, but also obtain marketable products from non-metallic components. article presents results experimental studies electric melting leaching tailings ore Almaly deposit containing by weight, %: 70.9 SiO2, 15.9 Al2O3, 2.1 MaO, 2.4 CaO, 3.6 K2O, 2.2 Na...

The paper deals with the commodity flows (production, import, export, consumption, prices) of manganese, chromium, silicon, vanadium, niobium, molybdenum, tungsten, titanium and nickel ferroalloys in dynamics from 2000 to 2019 throughout Russia. also specifies groups ferroalloys: import-dependent (silicomanganese, metallic ferroniobium), export-oriented (ferrosilicon, ferrochrome, ferrovanadium...

Nodular gray cast iron having properties superior to conventional can be produced by treating the molten so that, when cast, graphite will compacted rather than in flake form. One such treatment involves introduction of magnesium (Mg) into a bath composition. It is principal object present industrial experiments provide an improved process for ductile production. Another which permits efficient...
