[Introduction]: Gold CIL process (carbon in leach) is an efficient method of extracting and recovering gold from its ore cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lowers the gold mining operation cost and increases gold recovery rate to 99%, which is the first choice of modern gold mining and gold beneficiation plant.
After Crushing and Comminution, add the gold ore slurry into 9 Leaching Agitation Tanks, pour in cyanide solution in the first 2 tanks and Activated Carbon in the following 7 tanks for the reverse-absorption process--This design shortens the time period of gold staying in the cyanide pregnant solution and recovers gold in advance, which sees a faster investment return compared to other designs.

· Unlike cyanide or hot acid digestion, Nelson says the new process doesn''t damage equipment. More importantly, it could be used in locations where cyanide is banned.
Maximise recovery and minimise costs by measuring more than just cyanide, with Orica''s next-generation Cyantific™ analyser. Orica''s Cyantific™ analysers have been helping gold miners reduce their reagent costs for over 10 years, but there''s much more to leach recovery than cyanide measurement.
Leaching (Gold Dissolution) Once Vat is loaded with ore, is flooded with a leaching solution of a desired cyanide concentration (usually 600 to 1000 ppm) and pH between 10 to 11 at ambient operating conditions through the filter section of the floor or added to the top of the ore charge.
· Mining chemicals represent a niche area of supply but at the same time their use is almost universal across the industry. In this month''s im-mining Spotlight Feature Article, from the June issue of International Mining magazine, Editor Paul Moore looks at the players, challenges, and future horizons for the sector.

Combating Bisulfide Corrosion and Hydrogen-Induced Corrosion. The presence of ammonia, hydrogen sulfide and varying levels of cyanides in FCC main fractionator overhead systems means there is potential for corrosion. Corrosion mechanisms normally found are bisulfide corrosion and hydrogen-induced corrosion due to cyanides.
With carbon-in-pulp, the ore is finely ground and the gold is solubilised using a cyanide leach in a series of tanks. Carbon is then added which adsorbs the gold. This method has a high gold recovery percentage. Find Out More. Carbon-In-Leach.

· The optimal pH for reaction (3) is 8.5. Oxidation destroys free cyanide and cyanide complexes, except for iron cyanide complexes. One of the major disadvantages of this method is the potential for forming chlorinated organics. Some of the products (e.g. cyanogen (CN)2) are even more harmful and toxic than cyanide itself.
