Gold processing - Mining and concentrating |

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.
