摘要
通过对熔炼渣和吹炼渣处理工艺的全面分析,提出了基于物相分析的结焦预防和处理策略.研究结果显示,熔炼渣主要由铁和二氧化硅构成,铜含量较高,且随着吨矿氧量的增加,炉渣黏度也随之增加,流动性降低,导致结焦现象加剧,将吨矿氧量控制在140 m3以下,可有效减少铜的化学溶解损失,降低渣的含铜量,为底吹炼铜工艺的优化提供了新的理论依据和实践指导.
Abstract
Through a comprehensive analysis of the treatment processes of smelting slag and blowing slag,a coking prevention and treatment strategy based on phase analysis is proposed.The research results show that the smelting slag is mainly composed of iron and silicon dioxide,with a high copper content.As the oxygen content per ton of ore increases,the viscosity of the slag also increases,the flowability decreases,and the coking phenomenon intensifies.Controlling the oxygen content per ton of ore below 140 m3 can effectively reduce the chemical dissolution loss of copper,reduce the copper content of slag,and provide new theoretical basis and practical guidance for the optimization of bottom blowing copper smelting process.
