灰吹火试金法测定银矿中银的含量
|
摘要
研究建立采用灰吹火试金重量法测定银矿中金量和银量的测定方法,经过优化试验条件,增加了电感耦合等离子体发色光谱法扣除杂质对银的影响以及纯金和纯银补正,该方法金的回收率在98.90%-99.84%,银的回收率在98.28%-99.65%,该方法快速,准确,适用于银精矿中金和银的测定。
A method for determining the amount of gold and silver in silver ore by means of gray-blowing test gold was established. After optimizing the test conditions, the influence of the impurity deduction method on silver and the correction of pure gold and silver were increased. The recovery rate of gold in this method is 98.90%-99.84 %, and the recovery rate of silver is 98.28 %-99.65 %. This method is fast and accurate, and is suitable for the determination of gold and silver in silver concentrate.
