which gives it the ability to metabolize highly toxic cyanate into ammonium and carbon dioxide We used a proteomics approach to investigate the effects of cyanate on the metabolism of this bacterium...
The consumption of cyanide during processing operations is a major economic cost in the extraction of gold from its ores, while the discharge of cyanide wastes may result in significant environmental pollution Many factors influence the levels of consumption and discharge of cyanide, including ore mineralogy and lixiviant solution chemistry...
During the gold cyanidation process, cyanide can be lost from the leachate by various chemical rout Since cyanide is generally the most expensive reagent in this process, it is becoming increasingly important to monitor these cyanide loss The products of these cyanide losses include base metal cyanide complexes, thiocyanate and cyanate...

Potassium cyanide definition is - a very poisonous crystalline salt KCN used especially in gold and silver extraction from ore...
However, cyanate, the product of detoxification and other oxidation processes, may be reduced to cyanide in reducing environments, eg, deepwater discharge of cyanidation tailings This study shows that the reduction of cyanate to cyanide occurs and that the reduction rate increases with decreasing solution redox potential...
Additionally, the cost of treating cyanide can represent an important part of the total operating costs incurred during gold recovery A bankable, cost-effective solution to cyanide destruction is a major consideration from the early planning stages of a gold metallurgical plant...

gold mining raises personal circumstances of miners and a lack of access to resources and are not uniform across the spectrum of activity technical knowledge Gold is far easier to process, transport and sell than most other minerals, making gold mining using rudimentaty but hazardous technology a realistic proposition In many cases the miners...
May 15, 2017 0183 32 1 Introduction The adsorption and oxidation of cyanate anions have been studied at various electrode materials such as gold , , , , platinum , , , , silver , and copper , In some papers, the formation of adsorbed cyanate has been reported as a product of the electrochemical oxidation of several related substances such as cyanide , , thiocyanate , glycine , or semicarbazide...

A mathematical model of cyanidation heap leaching of cupriferous gold ores which includes the speciation of all cyanide, cyanate, thiocyanate, hydroxide and sulfate complexes, and their corresponding copper and gold precipitates, was developed to facilitate the treatment of these complex or...
If you have ever played an instrument or simply banged or hit any object you have dealt with harmonic resonance frequency Everything on Earth and in the universe vibrates at a certain frequency, but the vibration of the Earth as a whole is a different matter...
SGS is a leader in gold processing Our robust technologies and experienced staff ensure improved gold recovery, and an improved bottom line for your mining operation Cyanide leaching has been the industry standard for gold processing for more than 100 years...

No It is used in the refining and fracturing processing the ore to get the Gold out of the base rock Cyanide is used in a utility capacity, it is not a Gold or Silver by-product...
The fact that many millions of gold have been extracted by the cyanide process, during the last five or six years, from South African tailings which could not be profitably worked by any other method previously tried upon them, lends a peculiar practical interest to this branch of metallurgy...

Sodium cyanide is water-reactive Sodium cyanide decomposes on contact with acids, acid salts, water, moisture, and carbon dioxide, producing highly toxic, flammable hydrogen cyanide gas Sodium cyanide solution in water is a strong base it reacts violently with acid and is corrosive Sodium cyanide is incompatible with strong oxidants...
Gold has been called the most beautiful of all chemical elements Its beauty has made it desirable for use in jewelry, coins, and artwork for thousands of years It was one of the first pure metals to be used by humans Gold is one of the few elements that can affect politics and economics Wars have been fought over access to gold...

cyanate ion in waste solutions from gold-mining operation can be destroyed by treatment with hypochlorite ion in basic solution Write a balanced oxidation - reduction equation for this reaction...
Curve b in Fig 1 shows the cyclic voltammogram obtained with a gold thin film electrode with preferential 111 orientation denoted Au 111 -25 nm in the following in contact with a 10 mM NaOCN 008 M NaClO 4 solution As previously reported for Au 111 and Au 100 electrodes , a significant charge contribution associated with the presence of cyanate is superimposed on the voltammetric ....
The gold is fine grained, 1 to 5 micron, and is mainly encapsulated in the arsenopyrite and chalcopyrite accompanied by a minor late phase free gold mineralisation associated with a quartz-vein stockwork development within granodiorite Free gold is also found in the heavily oxidised 1660 1640 horizons...
