21-08-2020· Sodium cyanide is the most commonly used leaching chemical in gold extraction process. According to theoretical calculation, leaching 1 gram of gold only requires 0.5 grams of sodium cyanide. However, in most gold cyanidation plants, the consumption of cyanide is high, which is 50-100 times higher than the theoretical calculation.
conventional cyanidation process. Ore is crushed, finely ground, and cyanide leached in a series of agitated tanks to solubilize the gold values. Instead of separating solids from the pregnant solution, as in the traditional cyanidation process, granular activated carbon is added to the leached slurry.

CYANIDATION IN GOLD PROCESSING ALTERNATIVES TO CYANIDE IN GOLD PROCESSING THIOSULPHATE LEACHING Thiosulphate leaching is a process that removes gold from gold bearing ores without the use of cyanide. Although not as aggressive a leaching agent as cyanide, thiosulphate offers several technological
Taking the gold cyanidation plant with processing capacity of 100000 tons per year and gold grade of 7.5 g/t as an example, gold CIL process can save the investment cost of $486000 than the CIP process, reduce the capital backlog of $201700, save and recycle capital of $675100 in advance excluding the cost of activated carbon. Carbon Desorption.
08-05-2019· Cyanide leaching is a process in which solid natural gold in ore or beneficiation product forms a gold-cyanide complex dissolved in water under the combined action of a leaching agent, an oxidizing agent and a base, that is, a phase transformation process of solid phase gold. Chemical reaction formula for gold leaching: 4Au+8KCN+2H2O→4KAu (CN ...
08-06-2016· The gold cyanidation process is the most important method ever developed for extracting gold from its ores. The reasons the widespread acceptance of cyanidation are economic as well as metallurgical. It usually obtains a higher recovery of gold than plate amalgamation and is easier to operate than the chlorine or bromine process.
29-03-2019· Cyanide-zinc replacement Process (CCD method and CCF method) back to top. The working principle of cyanide-zinc replacement process is to use zinc powder (silk) as the reducing agent to replace gold and silver from the leaching liquid, which mainly includes four operations: washing (solid-liquid separation), purification, deoxidation,replacement.
12-08-2015· A common Cyanidation Process for Gold or called CIL and CIP. The amount of these two reagents in the slurry is very important, without enough cyanide to consume all of the valuable mineral there will be losses. Without enough lime a condition may developed that could potentially be very hazardous to the workers well-being.
20-10-2014· Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.
12-01-2021· "Traditionally, leaching or separating gold and other precious metals from an ore deposit or e-waste materials requires the use of cyanide," Eksteen said.
