TACEF GROUP, supplies steel and others mineral raw materials for different industries in the global market. Our steel concrete fillers can provide a typical density of between 3.0 t\/m3. Up to 7.2 t\/m3. When mixed with other iron-based materials. The concrete, adding our mixes, can reach a density of up to 7.2 t\/m3.\u200b<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Slage\u00a0<\/h2>\n

Ferrous slag can hold significant value as an industrial by-product, but its utilization depends on its origin, chemical composition, and physical characteristics. In smelting operations, it typically consists of a mixture of metal oxides, silica, lime, alumina, magnesia, and traces of entrapped metal.<\/p>\n

What is ferrous slag used for?<\/h2>\n

During smelting, slag plays a fundamental role: capturing and separating impurities from the molten metal. Fluxes, such as limestone or dolomite, help form a phase that concentrates these impurities and allows them to be removed from the metal bath.<\/p>\n

Once solidified, however, the slag can be processed to recover residual ferrous metal and utilize the remaining mineral fraction.<\/p>\n<\/div>\n

Gravel and Ballast<\/h2>\n

Gravel and aggregates are used for driveways, roads, railway tracks, asphalt production, and more. We supply quality crushed stone for projects of all sizes.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Fines<\/h2>\n

Metal fines from foundry processes are small particles of metal and oxides generated primarily during melting, pouring, cleaning, shakeout, grinding, and casting reclamation. Their utilization depends heavily on their composition and level of contamination.<\/p>\n<\/div>\n

\"\"

MillScale<\/h2>\n

Mill scale is a layer of iron oxides that forms on steel when it is subjected to high temperatures during processes such as continuous casting, reheating, and hot rolling. It is composed primarily of w\u00fcstite (FeO), magnetite (Fe\u2083O\u2084), and hematite (Fe\u2082O\u2083), with w\u00fcstite predominating in many cases.<\/p>\n

It is a particularly interesting by-product because it has a high iron content and relatively few impurities. Studies report Fe contents in the order of 70% or higher, although this must be verified through analysis of each batch.<\/p>\n<\/div>\n

Ferric Oxide<\/h2>\n<\/div>\n<\/div>\n
\n

Slag, metal fines, mill scale, and ferric oxide grit are our core products; they consist of 90% iron, making our specialty mineral by-products highly valuable and consistently high in quality.\u00a0<\/p>\n

It is naturally of medium density and also climate-friendly, as it requires less external energy input during beneficiation and pellet production. TG Minerals Group also operates one of the most energy-efficient pellet plants in the world, where we process iron ore primarily to produce blast furnace and direct reduction pellets, as well as fines.<\/p>\n<\/div>\n
