Due to the nature of the inpulp process, the following characteristics are important: High affinity towards gold – kinetic activity and equilibrium loading. Hard, resistant to abrasion. Density, suited to mixing in pulp.
Read MoreThe loaded carbon is then separated from the pulp by screens that are air or hydrodynamically swept, thus preventing blinding by the near sized carbon particles. The pulp residue is then either thickened to separate the cyanide containing solution for recovery/destruction of the cyanide, or sent directly to the tailings storage facility from

These are removed by thermal regeneration of the eluted carbon, typically in a rotary kiln at temperatures of 650–750°C. Regeneration is carried out in a steam atmosphere to minimize carbon degradation due to oxidation. The eluted and regenerated carbon is screened
Read MoreThe carbon in pulp method is only used where tank leaching is utilized for the recovery of gold from the ores and this is not the case in most large gold mines today, since heap leaching is the lowest cost method for recovering gold from ores containing from a few grams to 5 or 6 grams per ton.
Read MoreActivated carbon for mining industry is commonly utilized in the absorption of golden cyanide complexes in gold processing.This procedure can be put on the crystal clear answer via a fluidized bed column or take part in the process of leaching on the tank along with also the separation of carbon.
Read MoreBy replacing the Merrill–Crowe zinc cementation step, carboninpulp (CIP) and carboninleach (CIL) recovery provided a process that allowed the treatment of lower grade and problematic ores, at lower capital and operating costs and higher metal recoveries.
Read MoreIn the gold mining industry today, cyanide leaching is the prevailing method for solubilizing and recovering gold. Most of the new gold that is mined each year is processed via adsorption of gold cyanide onto activated carbon (Fleming et al. 2011). Typically, the carbon in pulp (CIP) or carbon in leach (CIL) process is used for gold recovery. These
Read Morefrom heaps. Down flow carbon columns are rarely used for gold recovery, because they act like sand filters and are subsequently subject to frequent plugging. 2. CarbonInPulp (CIP): Carboninpulp operation is a variation of the conventional cyanidation process. Ore is
Read MoreCarbon 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 appliions where the presence of competing silver or copper does not prohibit its use.
Read MoreThe carbon in pulp (CIP) process, The carbon in leach (CIL) process and The carbon in column (CIC) process. During the CIP process activated carbon particles are added to the leached pulp in a counter current circuit. The counter current principle is important because the amount of gold adsorbed on the carbon is in equilibrium with the
Read MoreThe most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon. Filtering the pulp through screens separates the goldbearing carbon.

Read MoreA process for treating refractory ores combines pressure oxidation treatment of the ore with cyanidation and carboninpulp recovery. Pressure oxidation is carried out under acidic conditions, at elevated temperatures and pressure.
Read MoreAfter the leaching process is complete, the soluble gold must be concentrated and separated from the process slurry. The method of recovery of gold from the process slurry is by carbon adsorption. Adsorption is a term used to describe the attraction of a mineral

Read MoreA process for adsorbing gold from a leach pulp by means of activated carbon is described in which the leach pulp (the leach solution together with the subdivided gold bearing ore) is diluted to a specific gravity of less than that of the activated carbon and is subsequently passed upwardly through a multistage liquid/solid contacting column.
Read MoreIn the absorption stage, this solution flows through several agitated tanks containing activated carbon. Gold absorbs onto the activated carbon, which flows countercurrent to the pulp, while screens separate the barren pulp from the goldloaded carbon. Carbonin leach (CIL) is a simultaneous leach and absorption process.
Read MoreCIL 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.

Read MoreJul 21, 2016 · This invention relates to the recovery of gold from carbon fines. Carbon fines are produced when carbon, which is used in a carboninleach (CIL) or carboninpulp (CIP) process for the recovery of gold, is broken. Typically, these fines, loaded to some extent with gold, exit from a last adsorption stage of the process and are then lost.
Read MoreIn 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 process used in resin recovery is similar to carbon, but the gold is adsorbed onto solid spherical polystyrene resin beads rather than activated carbon
