#0183;#32;Introduction Gold leaching from ores by hydrometallurgy method has been developed using several reagents. One of the most commercial reagents used for the gold extraction from the ore is cyanide solution1,2,3. The cyanidation method has high sensitivity, low operational costs and capable to extract gold up to 98%.
Metallurgical ContentLearn CyanidationDevelopments in the CarbonInPulp ProcessDesign Criteria Commercial Operations Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carboninleach. This is a

#0183;#32;Redox potential for gold leaching as a function of lead nitrate added. Preleaching: 30 min; cyanidation: pH, NaCN 710 mg/L, 02 15 ppm, 48 h. Fig. 8 illustrates the relationship between gold recovery and the reagents consumption expressed as the gross profit (extraction income less the cost of reagents: Pb(NO3)2, /kg; NaCN, /kg).

received attention and new rate equations expressing the gold leaching are still developed. The effect of leaching parameters on gold cyanidation is studied in this work in order to optimize the leaching process. A gold leaching model, based on the wellknown shrinkingcore model, is presented in this work. It is proposed that
After the gold extraction process, the final oxidized gold leaching rate reached %, and the sulfide gold leaching rate reached %. In order to recover useful minerals such as copper, gold and silver from tailings,a copper mine in Xinjiang, China decided to use a heap leaching method to treat tailings based on investment cost and process flow after multiple rounds of tests.

Cyanidation is used for gold that is distributed finely through a mineral matrix. Liberation: Cyanide leaching will only be effective if the cyanide can come in contact with the gold particle. For this to happen, the ore should either be sufficiently porous for cyanide to reach the gold, or more usually the ore is crushed and ground to a size at which the surface of the gold is exposed
The effect of Ag, Ni and Cu cyanides on gold adsorption on activated coconut carbon in cyanide leach solutions was investigated by synthetic cyanide leach solutions containing gold and other metal...

High temperatures also reduce the capacity of carbon to adsorb gold and lower the solubility of oxygen in the slurry. Therefore leaching and adsorption is conducted at ambient temperatures. Cyanocides and Oxygen Consumers Many other metals and minerals besides
#0183;#32;An alternative to conventional recovery processes for gold ( carbon adsorption, ion exchange, and solvent extraction) has been developed recently, namely the electrodepositionredox replacement (EDRR) method for selective gold recovery from cupric chloride leaching solutions (Lundstr#246;m and Yliniemi, 2017, Korolev et al., 2019, Korolev et al., 2018, Yliniemi et al., 2018b)
Adsorption recoveries vs. time at 5, 10 and 15 ppm Au solution concentrations According to Fig. 1 the adsorption of gold from solution on activated carbon is very fast up to 7 hours and slows down
Gold CIL amp; CIP Gold Leaching Process Explained CCD. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carboninleach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching
Pongkor Gold Mining Business Unit is CIL (Carbon In Leach) Process which cyanidation process occur. Pongkor has epithermal low sulfide and clay ore which have its own difficulty to process to get high gold extraction levels. There are many several variables in cyanidation process that can be optimized to increase gold extraction.
