At present, the volumes of use of electric arc furnace (EAF) dust are extremely insignificant. The volumes of their formation amount to thousands of tons per month. During storage, they have a negative impact on the environment. At the same time they are a material that has a valuable composition (oxides of iron, non-ferrous metals, etc.) and is promising for recycling. However, the secondary use of zinc-containing EAF dust in ferrous metallurgy leads to the accumulation of zinc in the lining of blast furnaces and frequent malfunctions.

从电弧炉粉尘中直接回收还原铁和锌

目前，电弧炉（EAF）粉尘的使用量极其微不足道。它们的形成量每月达到数千吨。在储存期间，它们对环境产生负面影响。同时，它们是一种具有有价值成分（铁的氧化物、有色金属等）并有望回收利用的材料。但在黑色冶金中二次使用含锌电弧炉粉尘，导致高炉内衬锌堆积，故障频发。
