技术简介

本技术为“钢铁烟尘及有色金属冶炼渣资源化清洁利用新技术”，以电炉灰、锌浮渣、铜镉渣、酸洗污泥等含重金属固危废为原料提取有价元素，攻克了以成熟、稳定的工业化技术对含重金属废物进行“脱氯除杂”的难题。该项技术从含重金属废物中提取出锌、铟、铅、镉、铋、等多种有价元素，以及铁精粉、还原铁粉等工业产品。

Introduction

This technology is a "new technology of resourceful clean utilization of iron and steel dust and nonferrousmetal smelting slag", using heavy metal-containing solid and hazardous wastes such as electric furnace ash, zincfloating slag, copper and cadmium slag, pickling sludge as raw materials to extract valuable elementsovercoming the problem of "dechlorination and decontamination" of heavy metal-containing wastes with matureand stable industrial technology, The technoloey extracts a variety of valuable elements such as zinc, indiumlead. cadmium and bismuth from heavy metal-containing waste, as well as industrial products such as ironconcentrate powder and reduced iron powder.
