Century Dictionary and Cyclopedia
- n. In chem., a combination of cyanogen with an element or a compound radicle capable of acting as an element. Potassium cyanide is the most important. It is a crystalline solid, permanent in dry air, but decomposed in moist air, giving off an odor of prussic or hydrocyanic acid. It has a bitter taste, and is extremely poisonous. It is extensively used in photography, electro-metallurgy, and as a laboratory reagent.
- To treat an ore with a weak solution of an alkaline cyanide, as in the cyanide process for the extraction of gold. See cyanide process.
