How Is Sodium Metabisulfite Used In Gold Mining?
Sodium metabisulfite is commonly used in the gold mining industry for a specific purpose, primarily in the process of gold extraction. Its application is related to the treatment of ores and the recovery of gold from ore concentrates. Here's how sodium metabisulfiteChina is typically used in gold mining: Gold Ore Leaching: Sodium metabisulfite is often employed in the gold ore leaching process. This process involves treating gold ore with a leaching solution, typically containing sodium cyanide. The sodium metabisulfite is added to the solution to reduce any excess or residual cyanide, which is crucial for the safety of the environment and workers. Cyanide Detoxification: Gold is often found in low concentrations in ore, and extracting it involves the use of cyanide solutions. After gold extraction, it is important to detoxify the remaining cyanide to prevent environmental contamination. Sodium metabisulfite is used to chemically reduce and neutralize the residual cyanide in
