A 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.

2022-3-15 1. Introduction. Gold extraction by cyanidation has been developed and continuously undergoing improvement for more than one century. Cyanide, however, is a highly toxic reagent that causes potential environmental hazards resulting from its mismanagement (Hilson and Monhemius, 2006).With the improvement of people’s awareness of environmental protection,

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

2021-6-25 To make the gold heap leaching process successful, the heap leaching material must have good permeability so that the cyanide solution can evenly pass through the ore pile. Most ores need to be crushed to 25.4mm or finer before granulation in order to expose the gold contained in the ore and improve the gold recovery rate.
