  • Gold processingMining and concentrating Britannica

    With ores of higher gold content (i.e. greater than 20 grams of gold per ton of ore) cyanidation is accomplished by vat leaching which involves holding a slurry of ore and solvent for several hours in large tanks equipped with agitators. For extracting gold from low-grade ores heap leaching is practiced.
