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.
Outotec''s cyanide leaching plants are available as gold adsorption directly from the process slurry in carboninleach (CIL) and carboninpulp (CIP) processes. In addition, dissolved gold can be recovered from the solution after solidliquid separation by MerrillCrowe and carbonincolumn operations.
the various methods of CIP cleaning. Finally it takes a brief look at new CIP technology using electrochemically activated water in cleaning and sanitising solutions. Together with its other processing solutions, SPX offers a ... CIP and Sanitation of Process Plant Design for cleanability
Cyanidation, or the metallurgical process of extracting gold from ore with cyanide leaching agents, has long been a primary method of gold used throughout the world, one incredible material helps to make gold recovery from a cyanide solution possible; with its ultraporous structure, activated carbon is a powerful adsorbent used throughout a number of industries to ...
Although the era of CIP commenced in the late 1970s, the use of carbon for the recovery of gold was recognized and practiced much earlier. Davis (1880) patented the use of wood charcoal for gold recovery from chlorination leach liquors, with this process subsequently used at Mount Morgan, Australia, in the early 1890s.
The process is highly effective for removing gold from low grade ore. Resin Recovery Technologies Resin RIL (Resininleach)/RIP (Resinin pulp) In recent years, resin is replacing carbon as the gold recovery substrate of choice. SGS is the world leader in the development of this technology.

CarrierinPulp (CIP) method, which is similar in principle with the CarboninPulp technology for gold recovery from ores, was proposed to recover these heavy metals from molten fly ash. Unlike the traditional CarboninPulp process, the carrier or adsorbent in the CarrierinPulp method is not only limited to carbon; other materials such as ...
The paper presented outlines the scientific approach taken to improve the metallurgical efficiency of a modern plant at Athens Mine. The plant is based on the CIP method of gold recovery with copper concentrate as a major byproduct. In the early stages of the operation the overall gold recovery achieved averaged 61% and copper recovery was 74%.
Jun 13, 2014· The APT Tritank is a step away from the conventional and a breakthrough in the cyanidation method of gold recovery. The distinguishing feature of .
This case study performed at the largest gold mining village in the Philippines compares four methods for gold recovery: amalgamation, cyanide leaching, a shaking sluice, and Cleangoldmsluices. The results show that a combination of manual panning or Cleangoldmsluices followed by cyanidation is the best solution under present condi
Carbon adsorption is increasing using in newer plants for gold recovery. Carbon in Pulp (CIP) technique involves contacting the leached pulp with granular carbon in a series of agitating tanks with a sufficient retention time. Selected summary of patented gold recovery processes and examples of .

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.

Aug 13, 2019· Difference between CIL and CIP: * CIL is adsorbed while leaching; * CIP is first leached and adsorbed. 1. CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed...
Typically, the next step in the recovery circuit is CIL, CIP or CIC leaching. Each of these methods utilizes a cyanide solution and activated carbon to extract the gold from the slurry. The applied technology varies from plant to plant, with CIL being the most widely used processing method. In a CIL leaching circuit, a
Gold is dissolved by the cyanide and then removed from the heap or columns. It is then extracted from the pregnant leach solution by adsorption on carbon or resins. This costeffective, proven method of ore extraction provides maximum recovery for many gold ores, .
