The process has evolved through work at Hazen Research, Inc. for Kamyr, Inc. and in brief, the consists of utilizing oxygen rather than air in the carbon-in- leach (CIL) process. We refer to this improved process for all ores amenable to cyanide leaching as carbon-in-1each with oxygen or CILO.

Cyanide leaching in the gold extraction process The two steps of slurry and activated carbon adsorption are one step, which reduces the loss while reducing management costs. Compared with the traditional CCD process, it saves 66% of the investment cost. It is the main process of modern gold ore dressing.

Add the gold ore slurry into 9 leaching agitation tanks, pour in cyanide solution in first 2 tanks, activate carbon in the following 7 tanks for the reverse-absorption process (the number of tanks depend on the capacity size).

Carbon-in-leach (CIL) is a simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain pre-robbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold meant for the activated carbon.

Outotec's cyanide leaching plants are available as gold adsorption directly from the process slurry in carbon-in-leach (CIL) and carbon-in-pulp (CIP) processes. In addition, dissolved gold can be recovered from the solution after solid-liquid separation by Merrill-Crowe and carbon-in-column operations. The most suitable technology is ...

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%. It has become the first choice of modern gold mining and ...

The process design of gold leaching and carbon in pulp Carbon in Leach CIL process is widely used in the mining industry and in particular, it is an integral step of gold processing in gold extraction.

Carbon-in-leach (CIL) is a simultaneous leach and absorption process. How is gold stripped from carbon? The desorption of gold from activated carbon is promoted by adding organic solvents to aqueous cyanide solutions. … Typically, gold is stripped from the carbon in 4-6 hours in 1 bed volume of solution to give concentrated gold eluates.

The main disadvantage of CIL is the inconvenience and labor costs. For CIL, carbon must be added to crude/solvent tincture and agitated for 20-30 minutes. Carbon is added to the tincture in 3-4 portions to promote better adsorption. This is because carbon's affinity to certain particles changes as the carbon pores are used up.

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 well. Gold 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 high-grade silver.
