When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.

Plant Residues

Plant residues provide the major source of SOM, and their biodegradation is critical to ecosystem productivity. Because plants typically contain up to 60% cellulose (Kögel-Knabner, 2002), the decomposition of cellulose is a key activity of soil bacteria and is vital to the energy flow through soils and the cycling of N, P, and S, where immobilization generally accompanies cellulose decomposition.
