The use of 6 tons of cyanide a day to extract the precious Argentine gold. The tons of cyanide used over 10 years for the extraction operations: 180 tons a month of sodium cyanide and other chemicals, such as 12 tons of chloridic acid, 12 tons of caustic soda, Kg of litharge and so on. The use of about a million litres of water a day.
Jan 21, 2015· Cyanide is usually found in compounds (substances formed by joining two or more chemicals). Cyanide can interact with metals and other organic compounds (compounds that include carbon). Sodium cyanide and potassium cyanide are examples of simple cyanide compounds. Cyanide can be produced by certain bacteria, fungi, and algae, and is found in a number of foods and plants.
What is the Effect of Aeration on Gold and Silver Leaching. Another of the prime requisites of successful cyanidation is free oxygen. Pure oxygen is too expensive to use, instead atmospheric air is the customary source of the required oxygen gas. Some interesting experiments have been conducted using Ozone but the practice has not been adopted commercially on account of the cost in the gold ...

Plants play an essential role in a gold mobilization. Many tropical plants produce, during metabolism, cyanide and humic acids. Precipitated gold particles are very small, and are distributed like a cloud in the alluvium. The gold in such alluvial deposit tend to be distributed through a complete vertical section.

Cyanide spill shuts Simberi mine Papua New Guinea Mine Watch. Mar 09, 2011· By Harlyne Joku The Department of Environment and Conservation (DEC) has ordered Allied Gold limited, operator of the Simberi Gold/Copper mine in the New Ireland Province to shut down its mill plant following a cyanide spill from one of its deep sea tailings disposal tanks last Tuesday.
The reactions that take place during the dissolution of gold in cyanide solutions under normal conditions have been fairly definitely established. Most agree that the overall cyanide equation for leaching and cyanidation of gold is as follows: 4 Au + 8 NaCN + O2 + 2 H20 = 4 NaAu(CN)2 + 4 NaOH
