Ferroalloy industries rely on minerals which are not available in pure form. The total value chain is very cost intensive and market driven. From mineral and environment conservation point of view every possible aspect must be explored for the economic utilisation of waste and low-grade ores. Unlike other metallurgical processes, Ferro alloys production generates a wide variety of waste rich in manganese/chrome which has a potential for recycling back. Fine size, high moisture content and presence of alkalis categorise this material into hazardous waste and economically non-viable. The challenge is to convert such anthropogenic material into a suitable feedstock for the furnace. In this article, the results of smelting trials carried out in electric arc furnace (EAF) using novel extruded briquettes (BREX) produced from the wastes of ferroalloy plant is discussed. The briquette produced by this technique exhibit high physical and metallurgical property and can replace the natural ore as a charge to some extent. Extruded briquettes (BREX) can be efficiently used as one of the essential charge component (up to 30% of the ore part of the charge) for the Silicomanganese smelting thus improving technical and economical parameters of the furnace and decreasing the self-cost of the Silicomanganese production.

铁合金工业依赖无法获得纯净形式的矿物。整个价值链非常耗费成本，且受市场驱动。从矿产和环境保护的角度出发，必须探索废物和低品位矿石的经济利用的各个方面。与其他冶金工艺不同，铁合金生产过程中会产生多种富含锰/铬的废料，这些废料具有回收利用的潜力。细小尺寸，高水分含量和碱的存在将这种材料分类为危险废物，并且在经济上不可行。挑战是将这种人为材料转化为适合炉子的原料。在本文中，讨论了在电弧炉（EAF）中进行的熔炼试验结果，该试验使用了铁合金厂废料生产的新型挤压成型团块（BREX）。通过该技术生产的团块具有高的物理和冶金性能，并且可以在一定程度上替代天然矿石作为装料。挤压团块（BREX）可以有效地用作硅锰冶炼的基本装料成分之一（最多占装料矿石部分的30％），从而改善了炉子的技术和经济参数，并降低了炉子的自成本。硅锰生产。
