MODULAR RECOVERY PLANTS
The Little Bald Mountain plant is typical of small ADR plants (Adsorption-Desorption-Recovery Plants) built by KCA. All operations needed for recovery of gold and silver from solution onto activated carbon, desorption, and electrowinning of metal bullion, are included in a 40-ft (12 meter) trailer or shipping container.

Cyanidation of Gold
Cyanidation of gold is a gold extraction method from the gold ore. It has been more than 100 years since the cyanide solution was used to leach gold from ore in 1887.The gold-containing solution obtained by cyanide leaching is called pregnant solution. It is commonly used to deposit gold mud by zinc replacement method or electrolysis method. Gold can be obtained by
