A procedure for the separation of gold from precious metal concentrates, based on its extraction by "dibutyl carbitol", is described. Spectrographic analyses indicate that the resultant metal is of high purity and tests have shown that recovery of the element is essentially quantitative. It appears that advantages could ensue from the incorporation of a scaled-up version of the procedure in an industrial process for the refining of precious metals.
本文描述了一种基于用“二丁基卡必醇”萃取从贵金属精矿中分离金的方法。光谱分析表明所得金属纯度很高，并且试验表明该元素的回收率基本上是定量的。看来将该方法的放大版本纳入贵金属精炼的工业过程中可能会带来好处。
