Leaching dissolves thegoldout of theoreusing a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically,goldin the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.

In cyanidation, metallicgoldis oxidised and dissolved in an alkaline cyanide solution. Whengolddissolution is complete, thegold-bearingsolution is separated from the solids. Withoresof highergoldcontent (greater than 20 grams ofgoldper tonne ofore), cyanidation is accomplished by vat leaching, which involves holding a slurry oforeand solvent in large tanks equipped with agitators.

The chlorine reacts with the gold inside the ore to form gold chloride. Filter the ore and bleach solution to remove all the impurities, such as soil and rock fragments. Collect the filtered gold chloride solution in a flask. Place powdered sodium metabisulfate in another flask and dissolve with water.

The addition of scrap iron to smelt mixes is a useful technique to small-scale operators experimenting with smelting techniques ongold-silver ores. It could also be used with small lots of sulfide concentrates. On the other hand, there are alternatives forprocessing sulfide ores.
