Examples
-
In 1863 Debus transformed hydrocyanic acid into methylamine with platinum black; however, this reaction is fugitive and soon ceases because cyanidation of the metal rapidly destroys its capacity to induce the reaction.
-
A gold ore may contain copper or arsenic, so as to debar cyanidation, where this process is the only hope of sufficiently moderate costs.

-
A flotation concentrator is added to allow for separate cyanidation of concentrate and flotation tailings.
-
Secon, the expanded cyanidation circuit is anticipated to reach 800 tpd, up from the current 425 tpd, within the first quarter of 2012.

The samples are shipped to the Abilab laboratory in Ougadougou, Burkina Faso, for analysis by bottle roll cyanidation on 1kg
-
The concentrate will be treated via pressure oxidation with subsequent cyanidation and Merrill-Crowe recovery of gold-silver dore.
-
We plan to process the refractory ore in our sulfide bio-oxidation plant at Bogoso and to process the non-refractory ore using our more traditional gravity, flotation and/or cyanidation techniques.
-
The concentrate will be treated via pressure oxidation with subsequent cyanidation and Merrill-Crowe recovery of gold-silver dore.
-
The sample preparation and analytical procedure involves pulverizing the entire 2kg (or less according to the material available) sample followed by quartering to obtain a representative 1kg (or less according to the material available) sample which undergoes bottle roll cyanidation for 24 hours.
