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 preg-robbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold meant for the activated carbon.

HEAP LEACHING TECHNIQUE in MINING

Jul 20, 2020· When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore …

The carbon is then removed by screening, across a carbon screen, allowing the liquid and finely ground ore (-100 mesh) to pass through easily, and retaining the carbon on the screen. The carbon is then generally subjected to a heated solution (200 deg to 250 deg F) of (1%) sodium hydroxide and (0.1%) cyanide and the gold is re-dissolved and ...

The carbon in the reactor into which pregnant pulp is fed (referred to as the first reactor) becomes highly loaded with gold. Loaded carbon values on operating plants range from 300 to 20 000 grams of gold per ton of carbon, a concen-trating factor of about 1 000–1 500. A portion of the loaded carbon is periodically removed from the first ...

How Is Gold Purified? | Sciencing

Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.

Many ores that contain gold contain other metallic metals in them also, so there are likely to be a lot of shiny minerals mixed into the rock which may or may not be valuable. The other challenge in visual inspecting gold ores for possible gold content is the fact that the total concentration of gold in a piece of ore is generally negligible ...

Preg

To understand the preg-robbing nature of the carbonaceous material I would also suggest doing preg-robbing index tests to determine how much gold is being re-absorbed back onto the ore and also comparing the results from direct cyanide leach tests with CIL tests to assess how effectively activated carbon is recovering preg-robbed gold.

Carbon in pulp

If the gold is a low grade ore, then it is broken up into chunks that are then put in carefully lined pads and treated with a dilute cyanide solution, which dissolves the gold. For high grade ore, the metal is sent to a grinding mill and made into a powder. Refractory ore contains carbon and is heated to over 1000 degrees F, which removes ...
