    Cyanide Solution an overview ScienceDirect Topics

    During cyanidation, alkaline cyanide solutions dissolve gold, silver, and other metals in order to form the respective anionic complexes which are stable in the solution. Cyanide ions can complex various precious metals and its reactivity is classified as follows (in decreasing order): Au, Ag, Nb, Pd, and Rh [6,8,9].The gold dissolution process occurs by various reactions which take place at

    POTASSIUM CYANIDE SOLUTION CAMEO Chemicals

    POTASSIUM CYANIDE SOLUTION is weakly basic. Reacts with acids of all kinds to generate quantities of very poisonous hydrogen cyanide gas. Incompatible with strong oxidizing agents, especially if solution dries out. Gives insoluble products with silver(I), mercury(I) and lead(II) ions that may decompose violently under certain conditions.

    Cyanide Copper Plating NMFRC

    cyanide solutions are used very little. Electroforming, with a few exceptions, is usually done from acid copper solutions. Printed wiring boards utilize electroless copper, acid copper and pyrophosphate copper, with the exception of one major manufacturer who used cyanide copper successfully on spe-cial boards for many years. Copper plate is also used as a dry lubricant in some wire drawing

    Destruction of Cyanide in Aqueous Solution by

    Fig. 3 shows COD removals of cyanide solution at the different pH values in electrochemical oxidation. The same trend was obtained for COD removal, but degradation of cyanide was faster by anodic oxidation at high initial pH than that at low initial pH. At initial pH 6, 8, 11 and 13, the rates of [COD] t /[COD] 0 are 51.8, 34.0, 24.2 and 15.8 % (COD removal, 48.2, 66.0 75.8 and 84.2 %) at 4 h

    Cyanide Wikipedia

    The cyanide salt absorbed in the basic solution is buffered at pH 4.5 and then reacted with chlorine to form cyanogen chloride. The cyanogen chloride formed couples pyridine with barbituric acid to form a strongly colored red dye that is proportional to the cyanide concentration. This colorimetric method following distillation is the basis for most regulatory methods (for instance EPA 335.4) used to analyze cyanide

    Cyanide Chemistry International Cyanide Management

    At a pH of 11, over 99% of the cyanide remains in solution as CN-, while at pH 7, over 99% of the cyanide will exist as HCN. Although HCN is highly soluble in water, its solubility decreases with increased temperature and under highly saline conditions. Both HCN gas and liquid are colorless and have the odor of bitter almonds, although not all individuals can detect the odor. Cyanide is very

    Cyanide control in the metallurgical process of gold

    oxygen are required in an aqueous solution in order to leach gold. For the leaching of pure gold, the stoichiometry of Elsner’s reaction gives the required molar ratio of free cyanide to oxygen as 8:1 (or 61/ 2:1 when expressed as a mass ratio). Since cyanide is the more expensive reagent, it is desirable from a financial point of view to ensure that cyanide is the rate-limiting reagent

    How to Prepare and Storage of Cyanide Solution

    The cyanide is usually dissolved in a little water before being added to the stock solution, as the amount of KCy present is more easily determined in a strong solution than in any other form. A special dissolving vat of small size is often provided and is placed at a higher level than the large vats used for the storage of the stock solution. High grade cyanide is now largely used containing
