1·Blister copper is the product of converter blowing. Under blowing and over blowing cause the copper unqualified.

铜锍吹炼的产物是粗铜，欠吹和过吹都会导致粗铜质量不合格。

2·This paper describes the experimental investigation on producing blister copper and recovering gold and silver by direct smelting of gold-bearing material.

进行了含金物料直接熔炼粗铜捕集回收金、银的试验研究。

3·The gold in blister copper sample was pretreated with nitric acid - sulphuric acid to remove copper, digested with aqua , and determined by flame atom absorbance spectrometry.

摘要本文建立了用硝酸硫酸预处理除去大量的铜，王水溶解，火焰原子吸收法测定粗铜中金的分析方法。
