【摘要】 本研究针对刚果金某高氧化率铜钴矿(铜氧化率56.92%、钴氧化率74.07%)伴生滑石等易浮脉石的难题，开展“预脱除—浮选—强磁选”联合工艺研究。采用预选脱除易浮脉石，在硫化矿浮选中创新应用硫酸铝、羧甲基淀粉组合抑制剂抑制滑石，配合丁基黄药、邻苯二甲酰双羟肟酸组合捕收强化氧化矿回收，尾矿经高梯度磁选进一步回收。研究表明该工艺可高效处理此类复杂矿石，具有显著工业应用价值。更多还原

【Abstract】 This research addresses the challenges of processing a high-oxidation-rate copper-cobalt ore（ Cu oxidation rate is 56. 92%,and Co oxidation rate is 74. 07%） containing talc and other naturally floatable gangue minerals. A combined “pre-removal-flotation-high-intensity magnetic separation ”process was developed. Pre-removal of easily floatable gangue was followed by sulfide flotation using an innovative Al₂（ SO₄）₃/carboxymethyl starch depressant system to suppress talc,while butyl xanthate/phthaloyl dihydroxamic acid collectors enhanced oxide mineral recovery. Tailings were further processed via high-gradient magnetic separation. The results demonstrate that this integrated process is highly effective for such refractory ores,offering strong potential for industrial application.更多还原
