Cyanide Leaching Of Gold
2013 1 3 The cyanide solution strength is also important in leaching gold, with the typical range of solution being in the 0.02% 0.05% NaCN. The gold particle size has a tremendous effect on the time required for dissolution in a cyanide solution. Generally, the finer the gold, the quicker it will dissolve. A 45 micron particle of gold would dissolve

The Metallurgy of Cyanide Gold Leaching – An Introduction
HTTPSA paper published by L. Elsner in 1846 first correctly identified the chemical reaction that forms the basis of all gold cyanide leaching processes: 4 Au + 8 NaCN + O 2 + 2 H 2 O → 4 Na Au CN 2 + 4 NaOH. The equation is well known, but the successful application of this reaction in a gold mining operation is rarely straightforward.
