offers 945 gold leaching plant products. About 44% of these are other mining machines, 30% are mineral separator, and 11% are leaching tank. A wide variety of gold leaching plant options are available to you, such as flotation separator, gravity separator, and sprial separator.
Approximately 85% of the gold is recovered in the plant. From the ball and/or autogenous mill, slurry is pumped to the CIL leach tanks where lime adjusts the pH, if necessary, and it is agitated for the desired period of time. Air is added to increase the reaction rate and shorten the leach time. Cyanide is added, typically in the first tank.
from plant to plant, with CIL being the most widely used processing method. In a CIL leaching circuit, a cyanide solution and oxygen are added to the slurry in large steel leach tanks. The gold dissolves from the ore into the solution. The activated carbon is fed into the process from the opposite direction, against the slurry stream.
For the leaching of pure gold, the stoichiometry of ... top tank to about 18 to 20 ppm in the second to fourth stages ... Figure 2—Cyanide/oxygen profile at Ergo CIL plant Figure 3—Diagram of a pipe sampler Air in Sample Out Slurry Level 6 m Pipe 1 m x 100 mm Filter bag.
Cyanide leaching is the standard method used for recovering most of the gold throughout the world today. The process originated around 1890 and quickly replaced all competing technologies. The reason was strictly economical in nature. Where amalgamation plants could recover about 60% of the gold present, cyanide could recover about 90%.
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 and adsorption take place in the same tanks. CIL is slightly different from another gold extraction process called CIP or carboninpulp process.
CIL gold processing plant mainly consists of following steps: 1 The ore is first reduced in size (typically 90% passing 200mesh ) to ensure that all nonrefractory gold is readily accessible for cyanide leaching, There are several variations of comminution circuits used in the gold leaching industry, such as: Multistage crushing, then ball milling circuits, typical of ball mill .
Gold Leaching( carbon in leach) process is widely used in the newly built gold leaching plants in recent years, and a lot of plants are changing into CIL as Leaching CIL process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content. It is unsuitable for the gold ore with highgrade silver.
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.
Leaching and absorption are simultaneous is the most outstanding feature of CIL process. Generally CIL has 610 stages of tanks. The sodium cyanide(or some other leaching reagent) solution is added into the first tank, and gold starts to be leached, most CIL plant will add the activated carbon from the second tank to the last one.

Finally, the CIL gold leaching rate is %, which brings considerable economic benefits to the mine owner. After the crushing and grinding stage of the CIL gold ore process, the slurry is added to 9 Xinhai highefficiency cyanide leaching tanks arranged in a stepped manner.
