Cyanide is historically found in sources such as certain plants (like bitter almonds and cassava), industrial processes (like electroplating and mining), and as a byproduct of combustion. However, it is not typically found in common food items like grains or dairy products. Therefore, the answer would be items or categories that do not naturally or industrially contain cyanide.
The extraction of gold and in electroplating of metals.
Cyanide compounds are widely used in the mining industry, particularly in the extraction of gold and silver through a process known as cyanidation. They are also utilized in the production of various chemicals, such as plastics and pharmaceuticals, and in electroplating and metal processing. Additionally, cyanides can be found in certain agricultural applications and as a byproduct in the combustion of nitrogen-containing materials. However, due to their toxicity, their use is heavily regulated.
In industry, cyanide compounds are widely used during the extraction of gold and silver from ores through processes such as cyanidation. This method involves dissolving the metals in a cyanide solution, allowing for efficient recovery. Additionally, cyanides are utilized in the production of various chemicals, electroplating, and as a precursor in the synthesis of certain plastics and dyes. Due to their toxicity, strict regulations govern their use and disposal to minimize environmental and health risks.
A common electroplating solvent is a solution of the metal salt that will be deposited onto the object being plated. Common examples include copper sulfate for copper plating, nickel sulfate for nickel plating, and silver nitrate for silver plating.

Most commonly a gold cyanide salt of some sort.
Sandia National Laboratories in Albuquerque developed methods for gold-plating onto microelectronic devices that did not use cyanide.
The most useful: GPC, gold potassium cyanide solution gold ammonium sulfite solution
AuCN3 is the chemical formula for gold(III) cyanide, which is a coordination compound made up of gold ions bonded to cyanide ligands. It is a highly toxic substance primarily used in gold electroplating and as a reagent in chemical synthesis.
Gold-VA is a strong acidic cyanide based gold-electrolyte.It is used in gold plating.

A common electrolyte bath will normally contain either a potassium-cyanide solution or a cyanide-free solution based on sulfites or chlorides.
The chemical compound Ni(CN)₂ is called nickel(II) cyanide. It consists of nickel in the +2 oxidation state and two cyanide ions (CN⁻). This compound is typically used in electroplating and in various chemical syntheses.
Potassium cyanide is not used in the cremation process. Any trace amounts of cyanide found in cremated remains would likely come from environmental exposure prior to cremation, rather than being a byproduct of the cremation process itself.
Cyanide is commonly used in industry for processes such as gold and silver mining, electroplating, and the production of plastics and textiles. It is also used in chemical manufacturing to create various compounds.
