摘要：

This article compares the total amount of fuel used in making steel from dispersed iron-bearing metallurgical wastes by different alternative technologies. Recycling such wastes by briquetting them and then smelting the briquets in blast furnaces is shown to be clearly more advantageous from an economic and environmental standpoint. The availability of excess pig-iron production capacitor at a metallurgical plant allows the plant to recycle the given type of wastes by the most cost-effective means while also reducing emissions of greenhouse gases. Similar results can be obtained by smelting the briquets in cupolas.
