CYANIDE PROCESS Meaning and
Definition
-
The cyanide process, also known as the cyanidation process, is a metallurgical technique used in the extraction of gold and silver from low-grade ores or minerals. It involves the utilization of cyanide compounds, particularly sodium cyanide, to dissolve the precious metals present in the ore, allowing their subsequent recovery.
In this process, the crushed ore is mixed with a dilute solution of sodium cyanide, usually in water. The cyanide forms a complex with the gold or silver, known as a "cyanide complex." This complex is soluble in water, enabling the extraction of the precious metal. The ore slurry is agitated or stirred to ensure adequate contact between the cyanide solution and the particles containing the valuable metals.
The cyanidation process typically takes several hours to several days, depending on the specific ore and desired metal recovery. After the desired extraction is achieved, the slurry is filtered to separate the liquid containing the dissolved precious metals from the solid materials. The solids, known as tailings, are usually disposed of in a secure manner to avoid any environmental or health risks associated with residual cyanide.
Cyanide processes have been widely used in the mining industry for over a century due to their efficiency in extracting gold and silver. However, they have also been subject to controversy and concern related to their potential environmental impact. Proper safety measures and regulations are implemented to minimize the release of cyanide into the environment and ensure the protection of human health.

Etymology of CYANIDE PROCESS
The word "cyanide process" can be broken down into two parts: "cyanide" and "process".
1. Cyanide:
The term "cyanide" comes from the ancient Greek word "kyanos", meaning "dark blue". It refers to a compound called cyanogen, which was a blue pigment derived from the oxidation of the dye-plant extract, known as "woad". "Cyanogen" is a compound consisting of carbon, nitrogen, and is highly poisonous.
2. Process:
The word "process" derives from the Latin word "processus", meaning "a marching forward", or "progression". In this context, it refers to a series of actions, steps, or procedures aimed at achieving a particular outcome.
Combining the two parts, the "cyanide process" refers to the specific method or series of steps used to extract gold and silver from their ores using cyanide solutions.
