试样用含亚硫酸钠的10％硫酸溶液浸取，使铜的氧化物矿物选择溶解，过滤后加入溴素掩蔽砷和锑等金属，补加少量硫酸，蒸干后用硫酸溶解，采用碘量法和电重法对比分析。本文采用十四个生产试样，两种方法对比，结果稳定，可靠。
試樣用含亞硫痠鈉的10％硫痠溶液浸取，使銅的氧化物礦物選擇溶解，過濾後加入溴素掩蔽砷和銻等金屬，補加少量硫痠，蒸榦後用硫痠溶解，採用碘量法和電重法對比分析。本文採用十四箇生產試樣，兩種方法對比，結果穩定，可靠。

The method involves decomposing the sample by treating it with sulfuric acid( 10% ) which con-tained sodium sulfite , and the oxide of copper is dissolved selectively . After filtering , add some bromine to mask arsenic , antimony and etc . Add little sulfuric acid and evaporate to dryness . Salts are dissolved using sulfuric acid and water . Using iodometric method and electro gravimetric method to analysis for compari-son . The text choose 14 production samples , comparing with the two methods , the results are stable and reliable .
