2Theoretically it would take 98.04g of sodium cyanide NaCN or 130.22g of potassium cyanide KCN to combine with 196.967g of gold to form either NaAu CN 2 or KAu CN 2. In practice since cyanide chemicals are fairly unstable and due to the fact that there are several chemical steps in the process it will probably take some extra cyanide.
Reviews from our electroplating gold mining and organic synthesis clients show that our potassium cyanide is the best in the market. We supply our potassium cyanide in many forms –powder tablets and liquid form. If you buy in powder form you can quickly dissolve it in water to form a liquid.

Potassium Cyanide 18.75 g/l 2.5 oz./gal. MAKE-UP PROCEDURE CAUTION Hazardous cyanide-containing chemical. 1 Add deionized water to a clean tank. 2. Add Super Strip 300 and mix thoroughly. 3. Add potassium cyanide and mix thoroughly. 4. Add deionized water to volume. Note: Sodium cyanide can be used in place of potassium cyanide. If sodium
of potassium cyanide consumed inoreased more slowly as the solution grew stronger potassium cyanide. In experiment three the atrenght of the sol ution in potassium oyanide and in gold was kept con stant at. O.20 and. 0.50. oz. respectively. To this sol ution varying amounts. or. ammoniaoal sapper hydroxide were added. The preoipitation
4. Gold loss to a minimum: one hand adopting electrolysis method to produce gold potassium cyanide can greatly reduce the loss of gold on the other hand a bit gold in the exhaust gas also recovered by the waste water recovery tank. Traditional method of making method
Sodium or potassium cyanide with probably sodium peroxide. No alkali required the 25g or so of cyanide tablet will give a pH of over 11 in the less than 2 litres of water shown. At that concentration the solution will as shown take up both gold and copper plating very quickly. Nothing particularly new or novel in the appli ion as shown. Deano
In a 0.25% potassium cyanide solution of gold from rejected gold plated 2 with oxygen bubbling at 5 5 X the rate of dissolution transistor cans gold coating 8 microns thick was determined to be about 2 m A / c m 7.5 X 1 0 " mole h r - c m . 5 2 or ELECTRONICS 171 Based on this rate we can estimate the time needed to dissolve a gold
Industrially it& 39;s usually made by reacting prussic acid hydrogen cyanide with potassium hydroxide. That won& 39;t help you if you& 39;re planning to make it yourself since the usual laboratory
I have available gold from electronics. I have been studying the basics of plating. There are complete plating kits but it is not the same. I& 39;m am in the process of making a work station with a dedi ed fume hood and scrubber just to work with small batches of cyanide using the the process to make my own cyanide leach from ferrocyanide.
Gold potassium cyanide making machine for electroforming processes. Function: for the production of the purity of 68.3% gold salt the gold salt is the materials of electroforming. Equipment configuration. Rectifier electroforming power Titanium anode and hode ; Anion and ion exchange membrane ; Heating and temperature control device

Step 3: preparation of fulminating gold Step 4: fulminating gold to gold potassium cyanide I want to know the more simple route to produce gold potassium cyanide in cost effective way.
In the method of preparing the bath an aqueous solution of potassium gold chloride KAu Cl 4 and potassium nitrate is prepared. Potassium cyanide is added to the solution and reacts with the potassium gold chloride to form a gold cyanide complex. Ethylenediamine hydrochloride is then added to the solution.
Gold is normally electro deposited from a solution containing essentially a double cyanide of Gold and an alkali metal additional alkali cyanide free cyanide and other alkaline compounds. This solution is usually produced from gold potassium cyanide or sometimes from gold cyanide or gold potassium cyanide.
With low concentrations of potassium permanganate being added to the alkaline glycine system the researchers were able to leach 85.1% of gold from the ore deposit similar to the extraction by cyanidation at ambient temperature and using a substance known as a benign reagent according to Professor Eksteen.

article osti 5528817 title = Cyanide evolution from a potassium gold cyanide plating bath author = Antepenko R. J. abstractNote = When a gold plating console was installed in a production area at the General Electric Neutron Devices Department GEND the console was placed adjacent to a 10% H/sub 2/SO/sub 4/ activation bath.
Potassium gold cyanide is usually made in a batch process. If the amount of current passed through the cell is approximately equivalent to the initial charge of potassium cyanide in the anolyte the anolyte at the end of the reaction contains very little contaminants and will yield a very high purity product on cooling.
