摘要
采用王水+H2O2+NH4Cl+HF溶样体系封闭溶样法对金精矿进行预处理,制得样品溶液后以原子吸收法测定银;其测定范围<1000 g/t,RSD为4.5%,测定60个样品仅需3 h。该方法具有简单快速、成本低、对环境友好等特点,其分析结果可满足选冶工艺生产的要求。
Gold concentrate is pretreated with aqua regia ＋ H2O2 ＋ NH4 Cl ＋ HF dissolution system and silver-containing solution is synthesized, in which silver is determined with absorption spectroscopy method. The measurement range is lower than 1 000 g/t and RSD = 4.5 %. It takes only 3 hours to determine 60 samples. The method is fast, low-cost and environment-friendly. It can meet the demands of ore processing and smelting.
