The results of industrial tests of smelting sulfide copper concentrates on industrial oxygen using side and bottom tuyeres with a protective gas layer in the Pobeda smelting unit (PSU) at the Mednogorskiy Medno-Sernyy Kombinat (MMSK) are presented. Based on the analysis of the operating conditions of the PSU, the main results of the experimental meltings are discussed. The possibility of achieving the maximum charge throughput up to 475 ton/day with a specific oxygen consumption for the bottom tuyeres of 3250–3450 m3 /h is demonstrated. The copper content in slags varies in the range of 2.5–3.0%, the copper concentration in the matte comprises 38.68%, and the SO2 content in the exhaust gases equals 12.24 vol. %. The campaign duration of the bottom tuyeres was 4.6 days.

波贝达氧鼓风炉底风口冶炼硫化铜精矿技术工业试验

介绍了在 Mednogorskiy Medno-Sernyy Kombinat (MMSK) 的 Pobeda 冶炼装置 (PSU) 中使用带有保护气层的侧和底风口在工业氧气中冶炼硫化铜精矿的工业试验结果。基于对PSU运行条件的分析，讨论了实验熔化的主要结果。证明了在底部风口的特定氧气消耗量为 3250-3450 立方米/小时的情况下，实现最大装料吞吐量高达 475 吨/天的可能性。炉渣中的铜含量在 2.5-3.0% 的范围内变化，冰铜中的铜含量为 38.68%，废气中的 SO2 含量为 12.24 vol.。%。底部风口的运动持续时间为4.6天。
