the rise of alternative cyanide destruction methods foraug 22, · the current manufacturing process for electroplating and metal surface finishing relies heavily upon the use of cyanide. cyanide is typically employed to plate complex metals and is more tolerant to certain impurities than other substances. one of the drawbacks to using cyanide in a manufacturing capacity, however, is its extreme toxicity.alta cyanide destruction recovery optionsmore and more g plants around the world are being required by law to destroy cyanide in tailings. this paper evaluates the options and what influences the process selection for cyanide destruction and recovery. the cost effectiveness, comparison of common detoxification methods with advantages and disadvantages are explored.g cyanidation g cyanidation (also known as the cyanide process or the macarthurforrest process) is a hydrometallurgical technique for extracting g from lowgrade ore by converting the g to a watersoluble coordination complex.it is the most commonly used leaching process for g extraction.. production of reagents for mineral processing to recover g, copper, zinc and silver representsg cip process (carbon in pulp) is one of the gmay , · since using cip g extraction method, the g recovery rate has been greatly improved. for example, a copperleadzinc processing plant in russia recovered g from lead flotation tailings (containing 0. mg / l of g), increasing the g recovery rate by 3%. 3. recovery of gcyanide destruction methods and processescyanide destruction methods and processes. detoxification processes are used to reduce theestimated reading time 10 minscyanide destruction methods and processesjul 07, · detoxification processes are used to reduce the concentrations of toxic constituents in tailings streams and process solutions, either by dilution, removal, or conversion to a less toxic chemical form (sometimes referred to asdestruction or degradation in the case of toxic cyanide species). the objective is to produce an effluent that meets limits or guidelines that have been setdetoxification of cyanide in g processingtechniques are used for treating cyanide bearing effluents from g processing. the methods to degrade cyanide solutions can be divided into three major groups natural, chemical and biological degradation. the chemical treatments include oxidation, ion exchange and adsorption by activated carbon or natural zeolite, (kurama and catalsarik,
