摘要
本文研究一种经济的、适用于真空蒸馏任何含汞的汞金工艺。在全封闭的石墨坩埚里,任何含量的汞金直接被加热到1000℃以上,熔化成纯金。蒸发出来的汞,连续不断地蒸发并冷却成液体,几乎百分之百地被回收,不污染环境。
A vacuum distillation method is developed and chosen to distil gold from gold amalgam containing various quantities of mercury. Owing to its low cost and favourable applicability In an all-closed graphite crucible,such gold amalgam is heated directly over 1000°C and is capable of melting to form pure gold.The mercury is recovered near 100% via continuous distillation and cooling to liquid phase.
