Gold CIL Processing Line
【Process Introduction】
Gold CIL (Carbon In Leach) Process is an efficient design of extracting gold from its ore. By cyaniding and carbon leaching,CIL process lower the gold mining operation cost and increase gold recovery rate.Click for Process Flow>>
【Application】
CIL mainly applies for the process of above 1g/t grade gold ore and gold ore with large bearing ore volume: silver, platinum, copper, etc.
【Process Description】
Mix gold ore pulp and cyanide
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.
reach a required concentration of standard
Filter Press and is used to increase gold ore slurry concentration.
Electrowinning
After the carbon leaching and Elution of gold, NaCN and NaOH solution is used for removing the gold from loaded carbon at a high temperature in electro winning cell and the metals are attached to cathodes.
