Abstract

This research focuses on studying the effects of the operating temperature and preconditioning time on the adsorption kinetics of sodium diisobutyl dithiophosphinate and sodium isopropyl xanthate collectors on the surface of galena, using contact angle measurements. The results indicate a strong correlation between higher operating water temperature and increased contact angles, suggesting faster adsorption kinetics and heightened hydrophobicity. Statistical analysis underscores the significance of temperature and preconditioning time, both factors being statistically significant. This study delves into the intricate interaction between temperature fluctuations and collector adsorption, contributing to a deeper understanding of flotation processes within the Pb/Cu circuit during seasonal temperature variations.

温度对方铅矿浮选过程中捕收剂吸附的作用:季节性温度和气候变化的影响
本研究利用接触角测量法,重点研究了操作温度和预处理时间对方铅矿表面二异丁基二硫代磷酸钠和异丙基黄原酸钠收集器吸附动力学的影响。结果表明,工作水温越高,接触角越大,说明吸附动力学越快,疏水性越强。统计分析强调了温度和预处理时间的重要性,这两个因素都具有显著的统计学意义。这项研究深入探讨了温度波动与捕收剂吸附之间错综复杂的相互作用,有助于加深对季节性温度变化期间铅/铜回路浮选过程的理解。 图表摘要
