Strike at a current density of 10 to 25 A/ft 2 for 2 to 3 min. at 110 to 120 °F, then

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 as"destruction" or "degradation" in the case of toxic cyanide species). The objective is to produce an effluent that meets limits or guidelines that have been …

1.1 Method 9010 is reflux-distillation procedure used to extract soluble cy anide salts and many insoluble cyanide complexes from wastes and leachates. It is based on the decomposition

Acid distillation procedures commonly used for determination of total cyanide in soil are inaccurate. Acid distillation only partially recovers insoluble metal-metal cyanide complexes.

operations. The IRMA Cyanide Management Chapter requires the same auditing procedures, and certified auditors, as for the Cyanide Code. CROSS REFERENCES TO OTHER CHAPTERS CHAPTER ISSUES 1.1—Legal Compliance As per Chapter 1.1, if there are host country laws governing cyanide transport, storage, use, etc.,

A summary of the state of the art of the processes used to reduce the toxicity and/or recycle spent potlining (SPL) is presented including some industries (cement, rockwool, and steel) that accept quantities of SPL. The authors have concentrated on processes that either are still active or have been developed to a pilot or preindustrial stage and have provided …

1. General Discussion In this section, cyanide refers to forms of inorganic cyanide (CN−) in water. Cyanide can exist in aqueous media as free undissociated hydrogen cyanide (HCN), free cyanide ion (CN−), and anionic complexes of cyanide with various metal cations. Hydrogen cyanide is a very weak acid with a dissociation pKa of 9.2. In water samples with approximately neutral pH, …

Hydrolysis of acetonitrile (the adding of water to its triple bond) is a useful synthetic procedure. Alkali metals such as sodium (Na) and potassium (K) attached to the cyanide group (carbon and nitrogen joined by three bonds, …

The acid boil should eliminate the zinc so your procedure sounds good to clean up the gold / zinc mixture. I seriously doubt that you are effectively destroying all of the cyanide using 2 gallons of Clorox for 2 pounds of Cyanide, plus you are not totally reducing the cyanide cyanate complex. The method to completely decompose the cyanide follows.
