Catalysis By Supported Gold Correlation Between Catalytic

Feb 14 2004 X-ray absorption near-edge spectra and temperature-programmed oxidation and reduction data demonstrate that AuI and Au0 are both present in working MgO-supported gold catalysts for CO oxidation. EXAFS data indicate gold clusters with essentially the same average diameter about 30 in each catalyst sample. Thus the results provide no evidence of an effect of gold

Extraction Of Gold Using Cyanide

the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble. To make gold soluble sodium cyanide NaCN is added and the cyanide ion forms a complex ion with the gold. This complex ion AuCN2- is readily soluble. Issues of gold extraction using cyanide
