摘要

摘要: 利用硫酸渣脫硫制備高品質鐵精礦具有良好的的工業利用價值，不僅可以解決燒渣的綜合利用問題，而且可以解決其對環境影響的問題.本文系統介紹了硫酸渣脫硫制備高品質鐵精礦的脫硫技術方法、工藝流程及最新研究進展.硫酸渣脫硫方法主要有化學法、聯合法和生物法.化學法主要包括酸浸、堿浸，聯合法可分為堿浸-酸浸、浮選-磁選、重選-浮選、磁化焙燒-磁選等聯合工藝方法.比較了這些方法的工藝路線及存在的優缺點，提出了生物法具有良好的工業應用前景，展望了該方法未來的研究方向為：高效脫硫菌種的選育，生物脫硫液的循環使用，硫酸渣生物脫硫協同回收有價金屬，生物脫硫過程基礎理論及工程化技術研究等.

Abstract: The preparation of high-quality iron concentrate from pyrite cinder by means of desulphurization has potential industrial applications. On one hand, the comprehensive utilization of pyrite cinder can be achieved, while on the other hand, the environmental problems that it causes can be solved effectively. In this study, the desulfurization technology and its process flowsheet, as well as recent advances, were summarized in detail. There are mainly three desulfurization methods, namely, chemical leaching, combined process, and bioleaching method. Chemical leaching mainly involves the acid leaching and alkali leaching processes. The combined process contains the alkali-acid leaching process, flotation-magnetic separation, gravity separation-flotation, magnetic roasting-magnetic separation, etc. The technical features of these methods were introduced, and it is concluded that bioleaching has a potential application value. The research areas of bioleaching method in a future will be included as:the breeding of effective desulfurization bacteria, cyclic utilization of desulfurization water, synergistic recovery of valuable metals, and basic investigation and engineering technology research in the bioleaching desulfurization process.
