ing the average gold extraction by 11.6% . This corresponds to a decrease in the average gold concentration in the washed residue of 0.3 g/t (0.01 oz perst) gold ore (Fig. 3). The results also proved the good economics of the PAL process. The value of the additional gold recovered exceeds the costs for

Calcination & Roasting Process. The usual method of process and treatment of the calcines (by calcination) from the roasting of gold ores is to cool in air, quench the moderately cooled material in water, and subject it to a light grind with pebbles or balls to break up agglomerated particles, sintered prills, etc.

Initially, bottle cyanidation tests are conducted on 200- to 500-gram charges of ground ore to determine the degree of gold extraction and reagent consumption. If the gold content of the ore is leachable at a relatively coarse grind, column percolation tests are made on ore crushed to various sizes, ranging from minus 2- to minus ¼-inch feed.

The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks.

Gold readily dissolves in these solvents because of the formation of complex ions that are very stable. Gold (Au) melts at a temperature of 1,064° C (1,947° F). Its relatively high density (19.3 grams per cubic centimetre) has made it amenable to recovery by placer mining and gravity concentration techniques.
