Gold on carbon/gold in solution ratios of gt;1000:1 are achievable in many cases. The distribution of that carbon between the stages (within reason) is irrelevant. The concentration of carbon in the pulp varies with the size of the tanks, so it is irrelevant. Gold extraction efficiency is determined by:
The sodium cyanide (or some other leaching reagent) solution is added into the first tank, and gold starts to be leached, most CIL plant will add the activated carbon from the second tank to the last one. Carbon segregation screen is set in every absorption tank''s outlet to separate the carbon and slurry.
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 gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.
between CIL and CIP.) The CIL process requires a larger carbon inventory in the circuit, which results in a larger inprocess tie up of gold. The larger carbon inventory can also result in higher carbon (and gold) losses through carbon attrition. CONCLUSION. Denver
the mechanism of gold adsorption is important because the CIP/CIL processes work as a result of the gold adsorption mechanism, which is a chemical occurrence. Factors that affect the adsorption of gold are discussed. Finally, performance monitoring methods that help control the operation of the CIP/CIL process are discussed. 2.
The solution of the CIL process has a higher gold grade than that of the CIP process because of the process structure. The CIL is leaching while adsorption, that means the dissolved gold is constantly fed into the solution, so the gold in the solution is constantly
The major difference between the CIL and CIP processes is; during the CIL process both cyanide leaching and carbon adsorption take place in the same tanks but in the CIP process first leaching
The gold grade in the solution in the CIL process is higher than the CIP process, which is determined by the process structure. The CIL process is composed of leaching and adsorption at the same time. So, the new dissolved gold constantly enters the solution, the gold in the solution is constantly replenished and the gold content in the solution is relatively high.
Process overview and description The CIP process A blockflow diagram of a typical CIP plant for a nonrefractory gold ore is shown in Figure 2. Table I and Table II illustrate the capital and operating cost breakdowns for a typical South African gold plant. These figures are not a
Difference between CIL and CIP 1CIL is adsorbed while leaching 2CIP is first leached and adsorbed [CIP (Carbon In Pulp)] CIP (Carbon In Pulp) is a carbon slurry The gold extraction method is a nonfiltered cyanide carbon slurry process directly adsorbing and recovering gold from cyanide pulp by using
Comparison Data With Sodium Cyanide . In order to probe the difference of leaching effect between NaCN leaching agent and CNFREE leaching agent on gold ore, ITAO select a total of six gold mineral samplesthe Sultan Kush oxidized gold ore, Tanzania(Busolwa Mining Ltd) oxidized gold ore, Tanzania (MMG GOLD LIMITED) oxidized gold ore and mixed ore (containing oxidized ore and primary ore
Gold CIP Production Line. Process Introduction. CIP (Carbon in pulp) process is a high efficient method to leaching and recovering gold from gold ore, The most different from CIL process is in CIP process, gold leaching and adsorption are separated, first leaching, and then adsorption. Now it is being replacing by CIL process progressively.
In CIP process, leaching and adsorption are two operations, the leaching tank is used for cyanide leaching of the slurry, and the carbon slurry tank is used for adsorption of gold by activated carbon. In CIL process, leaching and adsorption of slurry is an operation. These two steps are carried out in the same tank, so it is generally referred to as a leaching tank or a carbon slurry tank.
