摘要
火试金法测定铜精矿中金、银含量,针对火试金方法特点,分别在配料比、氧化铅用量、熔融时间、灰吹温度、铅扣大小这几个方面进行了研究探讨,确定了分析过程中最佳的试剂用量及配料比,从而解决材料消耗,环境污染等问题。
The content of gold and silver in copper concentrate was determined by fire assaying.According to the characteristics of fire assaying,the proportioning ratio,lead oxide dosage,melting time,soot blowing temperature and lead button size were studied,the best reagent dosage and proportioning ratio in the analysis process were determined,so as to reduce material consumption and environmental pollution.
