Key words: gold; silver; mercury; cyanidation; Knelson method The recovery of gold can be accomplished via thorough leaching, gravity, flotation, bioleaching, high pressure oxidation, roasting or combination of these methods [1].

Each of these methods strongly depends on the chemical and physical properties of ore, Cited by: 2. Alchemists—driven by greed and curiosity—did not manage to produce gold from cheap materials, but they certainly initiated and advanced chemical knowledge.

The reaction, known as Elsner's Equation, is: 4 Au + 8 CN-+ O 2 + 2 H 2 O = 4 Au(CN) 2-+ 4 OH-Although the affinity of cyanide for gold is such that it is extracted preferentially, cyanide will also form complexes with other metals from the ore, including copper, iron and zinc.

The process of cyanidation took place through the oxidation of sulfide to sulfur oxides and cleavage of the C–CN bond of acetonitrile.

The reaction was found to be catalyzed by vanadium pentoxid. EXCLUDING mechanical, smelting, and amalgamation processes, the methods of extracting gold from its ores may conveniently be grouped together under the heading of wet or chemical methods.

cyanidation[‚siənə′dāshən] (chemistry) Joining of cyanide to an atom or molecule. (metallurgy) cyanide process Cyanidation (also cyanide process), in hydrometallurgy, a method of extracting metals, chiefly gold and silver, from ores and concentrates by dissolving them selectively in solutions of alkali-metal cyanides.

Selective dissolution. Measurement of cyanide in different matrices including water, soil, air, exhaled breath, food and biological fluids (blood, urine, saliva, etc.) have been reviewed in official documents [1, 15], books [2,16] and journal articles [4, 17,18,19]; all are more than 5 years old (ref.
