Activated carbon effectively removes the gold from the cyanide, as the gold is adsorbed into the pores in the carbon. This has spawned technologies such as CIP (carboninpulp), CIL (carboninleach) and CIC (carbonincolumns). More recently, SGS has lead the gold processing industry with the development of resinbased technologies.
Takes on a triangular single tank design as opposed to the outdated multiple circular design = multiple benefits including enhanced metallurgical performance, smaller land footprint, less construction materials and reloion possible reducing "minetoprocess" transport costs.
Pulp flows continually from the first vessel to the last in the series, and the carbon is transferred intermittently by pumping in the opposite direction. Gold is washed (eluted) from the loaded carbon with a solution of cyanide and caustic soda, and then recovered by electrolysis or by precipitation with zinc dust.
if the pulp in this stage is contacted with unloaded carbon. The considerable difference in grain size between carbon and pulp particles permits an easy separation of the two by sieving. Whereas pulp particles generally do not exceed 100 microns, the carbon granules appear in fractions between 1 and 3 mm. Carbon in pulp process (p25).
The process design of gold leaching and carboninpulp saimm. liberation of gold, the circuits that will have the most effect on the successful operation of a gold plant will be that of the leaching and carboninpulp circuit (CIP).
In the CIP process, activated carbon is used to adsorb the gold directly from the cyanided pulp in a series of large adsorption tanks. Pulp flows continually from the first vessel to the last in the series, and the carbon is transferred intermittently by pumping in the opposite direction.
density on carbon performance is an important factor since at lower densities (less than about 1.46 kg/l), the carbon tends to sink (thus the reported carbon concentration is lower) and adsorption is adversely affected. While at high pulp densities (greater than about 1.46 kg/l), the carbon tends to float
Jul 08, 2013 · Hanlon Engineering was asked to design a CIC process plant to be constructed at a new mine in Northern Nevada. During this effort, HEA developed a
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.
The carbon in pulp (CIP) and carbon in leach (CIL) processes became firmly established in the gold mining industry in the 1980s, initially in South Africa and Australia, from where they spread rapidly to all the gold producing regions of the world. Minerals Engineering

Recently, it was again converted to a carboninpulp flowsheet. In retrospect, the original Carlton CIP was a forerunner of things to come and perhaps ahead of its time. John L. Fast is a registered professional engineer and has been involved in the design
CarboninPulp (CIP) and CarboninLeach (CIL) processes have surface areas of about 1000 m²/g i.e. one gram of activated carbon (the amount of which will occupy the same space as the end of a person''s thumb) has the same surface area as two football fields. The high surface area is contained in the millions of pores of varying sizes, these being
A Smarter Approach to CarboninPulp (CIP) and ResininPulp (RIP) Appliions. The Pumpcell circuit is a process route used for CIP or RIP appliions. The Pumpcell represents a new approach to the design of conventional cascade CIP adsorption circuits.
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching the gold ore slurry simultaneously, CIL process lower the gold mining operation cost, and increase gold recovery rate to a ratio of 98%.
Design Criteria . In the carboninpulp process activated carbon is mixed with a ground ore plus water slurry in which gold and silver cyanides are dissolved. After the precious metals are adsorbed onto the carbon, the loaded carbon is separated from the pulp and stripped.

ABSTRACT. Carboninleach and carboninpulp are continuous processes that use activated carbon in a cascade of large agitated tanks, which have been widely used to recover or concentrate precious metals in gold extraction plants.
The carboninpulp – i Design. The carboninpulp method also uses cyanide, but utilizes carbon instead of zinc to precipitate the gold. gold smelting. If the gold is still not pure enough, it can be smelted. Smelting involves heating the gold with a chemical substance called flux.

Three key areas of C.I.P. plant design, viz. leach ing time, adsorption and the gold loading on the carbon, are discussed and illustrated with examples. The need for accurate pilot plant data for use in assessing and optimising design is emphasized. This approach should minimize capital and maximise return on capital. It is demonstrated that,
