Jan 21, 2015· Cyanide is usually found in compounds (substances formed by joining two or more chemicals). Cyanide can interact with metals and other organic compounds (compounds that include carbon). Sodium cyanide and potassium cyanide are examples of simple cyanide compounds. Cyanide can be produced by certain bacteria, fungi, and algae, and is found in a number of foods and plants.
Oct 20, 2014· Liberation: Cyanide leaching will only be effective if the cyanide can come in contact with the gold particle. For this to happen, the ore should either be sufficiently porous for cyanide to reach the gold, or more usually the ore is crushed and ground to a size at which the surface of the gold is exposed – the gold is liberated.
A cyanide is a chemical compound that contains the group C≡N. This group, known as the cyano group, consists of a carbon atom triplebonded to a nitrogen atom.. In inorganic cyanides, the cyanide group is present as the anion CN −. Salts such as sodium cyanide and potassium cyanide are highly toxic. Hydrocyanic acid, also known as hydrogen cyanide, or HCN, is a highly volatile liquid that ...
information on cyanide leaching of gold leach plants > Cyanide Leaching Of Gold . Gold Cyanide Solution (Leaching Gold With Cyanide) Since the 1890''s, cyanide has been used to recover gold from gold bearing ores. And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the ...
Cyanide is manufactured and distributed for use in the gold and silver mining industries in a variety of physical and chemical forms, including solid briquettes, flake cyanide and liquid cyanide. Sodium cyanide is supplied as either briquettes or liquid, while calcium cyanide is supplied in .
Assuming that a gold ore has been effectively ground to ensure maximum economic liberation of gold, the circuits that will have the most effect on the successful operation of a gold plant will be that of the leaching and carboninpulp circuit (CIP). The reagent and utilities operating costs associated with leaching, adsorption, elution and ...

Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.
The secondary hydrocyclone (9) further classifies the slurry, with the coarse particles being directed to the ball mill (14) and fine particles reporting to the trash screen (10). The ball mill is very similar to the SAG mill, except it has a larger proportion of steel balls to assist in the grinding process.
