leads to the conclusion that gold actually occupies a unique position among the elements. There are several consequences of this effect in gold chemistry: 1. The color of gold. Gold has an absorption beginning at 2.4eV, attributed to a transition from the filled 5d band to the Fermi level (essentially the 6s band). It

The concept of amine basicity is discussed and used to explain the selective extraction of gold from alkaline cyanide solution. The apparent basicity of simple weak base amines with respect to Au(CN) 2 can be increased as much as 5 orders of magnitude by the addition of organic phosphorus oxide compounds (TBP, DBBP, etc.). It has been shown that …

The results of these studies, made on a large variety of ores, was to show in all cases a partial extraction of gold. This extraction varied from 20 per cent, to 95 per cent. While it was always easy to make a partial extraction of the gold, it proved difficult, and in many cases impossible, to get anything like a complete extraction.
