摘要
铜硫化矿火法冶炼通常由精矿熔炼、铜锍吹炼和粗铜精炼三部分组成,其中熔炼和吹炼按工艺方法可分为空间冶炼和熔池冶炼,近些年,熔池冶炼技术得到了快速发展。本文重点对熔池冶炼中的富氧底吹熔炼、富氧侧吹熔炼、底吹连续吹炼和多枪顶吹连续吹炼技术的发展现状、存在问题及解决思路和方案进行了论述,特别对提出的各种组合形式的连续炼铜工艺做了展望,指出连续炼铜技术和短流程工艺是未来铜冶炼的发展方向。
The pyrometallurgical smelting process of copper sulfide ore is usually separated into concentrate smelting, copper matte converting and crude copper refining, among which smelting and converting can be further divided into suspension smelting and bath smelting according to process method. In recent years, bath smelting technologies have developed rapidly. This paper expounds on the development status, existing problems, solutions and schemes of oxygen-enriched bottom-blowing smelting, oxygen-enriched side-blowing smelting, bottom-blowing continuous converting and multi-lance top-blowing continuous converting in bath smelting. In particular, the prospects of various combination of continuous copper smelting processes are analyzed, continuous copper smelting technology and short process flow are the development trends of copper smelting in the future is pointed out.
