5月份,矿冶院针对三贵口铅锌矿锌浮选指标下滑问题在乌后紫金开展技术攻关,确定将 “锌粗精矿再磨”调整为“锌中矿再磨”工艺,并对药剂制度进行优化,经工业调试,锌浮选指标明显改善,尾矿锌品位从0.3%以上降至0.25%以下,显著提高锌回收率,而且工艺稳定性更佳,成功实现成果转化。 

矿冶院选矿研究所先后5名科研人员深入生产一线开展技术攻关,联合乌后紫金专业技术人员,从实验室研究、验证再到工业试验,历时28天。为了加快项目进度,尽早解决企业难题,每人日均工作时间超12小时。

在实验室研究期间,根据前期工艺矿物学研究结果,详细开展 “锌中矿再磨”工艺、“锌快浮”工艺、“锌中矿单独再磨再选”工艺与实际生产“锌粗精矿再磨”工艺的对比研究。分析试验指标,并结合生产实际,推荐优先采用“锌中矿再磨”工艺替代现有“粗精矿再磨”工艺,并在选矿厂检修期间,迅速的完成“锌中矿再磨”工艺改造,进一步完善加药系统,优化药剂制度。我院科研人员全面跟班指导工业调试,一周内即顺利完成工业试验,达到预期指标。

该研究成果的成功转化应用,较大幅度的提高乌后紫金选矿厂锌浮选指标,降低药剂成本,可为企业创造可观的经济效益。
