摘　　要：在对刚果(金)某氧化铜矿石进行的硫酸搅拌浸出研究中取得了显著成果。研究表明,在常温常压条件下,通过调控磨矿细度、矿浆液固体积质量比、搅拌时间、硫酸质量浓度和搅拌速度等因素,成功获得了极具潜力的高铜浸出率。具体而言,在磨矿细度为-200目占86%、矿浆液固体积质量比为4∶1、搅拌时间为6小时、硫酸质量浓度为30 g/L、搅拌速度为200 r/min的工艺条件下,铜浸出率超过84%,稳定性高且可重复性强。这项工艺的突出优势之一在于其简便易行。通过合理调节多种因素,无需复杂的设备或技术条件即可达到理想的铜浸出效果,这为生产提供了便捷的操作手段。同时,其低成本特点进一步凸显了其实用性,无需昂贵的原料或特殊设备,从而节省了生产成本。此外,这一工艺方法对环境友好。相比其他传统的铜提取方法,减少了废水和废气的排放,极大地降低了对环境的污染,符合绿色、可持续发展的现代工艺要求。Significant achievements have been made in the study of sulfuric acid stirring leaching of a copper oxide ore in the Democratic Republic of Congo.Research has shown that under normal temperature and pressure conditions,high potential cop⁃per leaching rates have been successfully achieved by adjusting factors such as grinding fineness,slurry liquid solid volume ra⁃tio,stirring time,sulfuric acid concentration,and stirring speed.Specifically,under the process conditions of grinding fineness of-200 mesh accounting for 86%,slurry liquid solid volume ratio of 4:1,stirring time of 6 hours,sulfuric acid mass concentra⁃tion of 30 g/L,and stirring speed of 200 r/min,the copper leaching rate exceeds 84%,with high stability and strong repeatabili⁃ty.One of the outstanding advantages of this process is its simplicity and ease of operation.By adjusting multiple factors reason⁃ably,the ideal copper leaching effect can be achieved without the need for complex equipment or technical conditions,provid⁃ing a convenient operating method for production.At the same time,its low-cost characteristics further highlight its practicali⁃ty,without the need for expensive raw materials or special equipment,thereby saving production costs.In addition,this process method is environmentally friendly.Compared with other traditional copper extraction methods,it reduces the discharge of wastewater and exhaust gas,greatly reduces environmental pollution,and meets the modern process requirements of green and sustainable development.
