Sodium Cyanide Applications
Sodium cyanide is used in the mining and metallurgical industry in:
- It is used as a solid or in solution to extract metallic minerals such as gold, silver and other metals.
- In electroplating.
- For metal cleaning baths.
- In the hardening of metals.
In addition to:
- Used in developing photos
- Production of organic chemicals
- Manufacture of plastics.
- Boat fumigation.
Another application is as insecticides. It also serves as entomologists as an agent of slaughter in collecting the jars.
The substance decomposes on burning producing toxic fumes of nitrogen oxides. The substance is a strong base. Reacts violently with acids and corrosive to metals such as aluminum and zinc. Reacts violently with strong oxidants such as nitrates and chlorine compounds, causing fire and explosion hazard.
The substance decomposes in the presence of air, moisture or carbon dioxide, producing highly toxic and flammable hydrogen cyanide fumes.
