提高铅锌矿中伴生银回收率的试验罗科华1,赵志强1,贺政1,申士富1(1.北京市北京矿冶研究总院)摘 要:针对某铅锌矿伴生银回收率低的生产现状,进行提高银回收率的试验.根据矿石性质,采用提高磨矿细度,降低浮选矿浆碱度,添加选择性捕收剂BK901C等工艺措施,在不影响其他指标的情况下,银回收率从51.86%提高到85.43%.关键词:选矿工程； 铅锌矿； 浮选； 伴生银； 回收率......
EDTA滴定法测定铅锌矿中锌的不确定度评定卢业友1,杨芬1(1.贵州省黔南布依族苗族自治州都匀市贵州有色地质化验监测中心)摘 要:通过检测铅锌矿样品中锌的含量,对测定结果的不确定度的来源进行分析和对不确定度的分量进行评定.结果表明,本法测量不确定度的最主要来源为标定EDTA标准溶液浓度和重复性测量样品这两项引入的不确定度分量.所以在实际的分析过程中,可根据实际情况,采取相应措施,规范操作,提高检测分析人员的技术水平,从而保证测量结果的准确,可靠.当测试样品中锌含量为17.11%时,其扩展不确定度为0.10%(包......
