The loaded carbon from the CIL circuit will then be washed with a 3 percent nitric acid solution, neutralized with a caustic solution in two acid wash vessels, and pumped to two strip vessels. A solution of 1 percent sodium hydroxide and 1 percent sodium cyanide will be added to the strip vessels to strip the gold adsorbed on the carbon.

The Metallurgy of Cyanide Gold Leaching - An Introduction

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.

Lime use in gold processing - A review - ScienceDirect

A significant body of scientific literature has been devoted to the industrial use of cyanide in gold processing ( Adams, 1990; Marsden and House, 2006 ), in contrast to the dearth of publications on the use of lime in this important industry. This review, therefore, explicitly focuses on lime use in gold processing applications.

Interstage Screens - Eaglerock Machinery

The main difference between CIL and CIP lies in the extent to which gold is leached prior to carbon adsorption. In the CIL operation, carbon is added to the leaching tanks, therefore the leaching reaction and adsorption occur simultaneously. In the CIP process most of the leachable gold has been leached prior to the first adsorption stage.
