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 cost-effective, proven method of ore extraction provides maximum recovery for many gold ores, .
CIL stands for carbon-in-leach. 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 carbon-in-pulp process.
Gold CIP process adsorbs gold from cyaniding pulp by active carbon including 7 steps: leaching pulp preparation, cyaniding leaching, carbon adsorption, gold loaded carbon desorption, pregnant solution electrodeposit, carbon acid regeneration, leaching pulp. Gold CIP system is a useful gold recovery method in mineral processing.
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.
ores. For the conventional cyanide leaching process, pretreatment such as oxidation is required to achieve high gold recovery. Roasting is a relatively simple but not environment-friendly method; bio-oxidation technology seems to be more suitable for the oxidation of flotation concentrate.
ICP mass spectroscopy (ICP-MS). The choice of method will depend on a number of factors, for example, the technology that is available, the skill of the operator, sample type, cost of analysis, sample throughput requirements and the objective of the analytical result. New methodology for determination of gold and precious metals using the
The solution chemistry of copper in cyanide solution and various technologies for the recovery of copper and cyanide from barren gold cyanide solutions were reviewed in the paper. Direct recovery methods are mainly based on the acidification–volatilization–reneutralization (AVR) process or its modifications.
Today, cyanide leaching is the method of choice for the recovery of most of the world's gold production. There are however, many other chemical leaching processes that have been sporadically or historically used. In most instances, cyanide leaching will provide a more technologically effective and cost efficient method. Alternative lixiviants ...
the various methods of CIP cleaning. Finally it takes a brief look at new CIP technology using electro-chemically 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
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.
This case study performed at the largest gold mining village in the Philippines compa-res 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-
The process is highly effective for removing gold from low grade ore. Resin Recovery Technologies Resin RIL (Resin-in-leach)/RIP (Resin-in 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.
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 by-product. In the early stages of the operation the overall gold recovery achieved averaged 61% and copper recovery was 74%.

gold from loaded carbon were developed, that the process came into widespread use for gold recovery from ore. These procedures allowed the carbon to be recycled for further gold recovery. Today, many options are available to the recovery plant designer and operator for the stripping of gold from carbon. Each method has advantages and ...
Carrier-in-Pulp (CIP) method, which is similar in principle with the Carbon-in-Pulp technology for gold recovery from ores, was proposed to recover these heavy metals from molten fly ash. Unlike the traditional Carbon-in-Pulp process, the carrier or adsorbent in the Carrier-in-Pulp method is not only limited to carbon; other materials such as ...
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 .

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
Among them, Gold recovery is very important and in the present times, most of the Gold mined is recovered through this method only. We at Boyce Carbon, have special grades of Activated Carbon that is specifically made for the Gold Mining Industry to recover more Gold from even feeble mines that have Gold in the ppm levels.
