1.Understanding the concept of CIP or CIL gold processing plant. CIP (carbon in pulp): after you leaching the gold ore pulp in the leaching tank by cyanide, then feeding the leached ore pulp into the adsorption tank for adsorp the gold by active carbon. CIL (carbon in leach) : feeding the ore pulp in to the leaching-adsorption tank, then leaching and adsorp the …
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 …

Hello All, I work in a CIL plant, processing oxide ore with more and more intrusion of sulphides (fresh ore body). The plant is designed for oxide ore but we noticed that at a certain blending, the transitional ore could be processed. It impacted on the gold recovery (going from 83-84% for pure oxid
The Main features of the CIL system: 1. CIL tanks The leach circuit comprises eight stainless steel tanks in series, located outdoors. Each tank is equipped with an agitator. The first tank is a pure leach tank and the following seven are CIL tanks. The flotation tailings slurry is pumped to the fist tank via a trash screen.

The most likely reason your no 8 CIL tank has lower oxygen than your no 2 tank is that the oxygen is being consumed with the presence of some sulfide minerals and oxidizing the sulfide to sulfate. Some sulfide minerals are more apt to consume oxygen than others and fine grinding will expose more surface area and increase oxygen consumption.
Options for an RO Plant without a CIP System. Large-scale facilities often have a centralized CIP system. A centralized system is automated with multiple cleaning circuits. It delivers cleaning chemicals to the whole facility. You can get the benefits of a CIP system in an RO plant even without a centralized system. Mobile CIP Skid
RTD curves were generated using sampling data collection method to monitor the radiotracer at tank outlets. The measured RTD data were treated and the Mean Residence Times (MRTs) of material in the tanks determined. For each tank, the experimental MRT calculated from the method of moments exceeded the corresponding theoretical MRT.
Construction in Progress (CIP) is a fundamental concept in the construction industry, encompassing the entire lifecycle of construction projects. From the initial planning and design stages to the final completion and handover, CIP provides a structured framework for project management, resource allocation, and timely execution.
These methods are Carbon -in-L each (CIL) and C arbon -in-P ulp (CIP). CIL and CIP operations have a number of adsorption tanks placed in series. Pulp flows continuously from the first tank to the last, while carbon is pumped counter current from the last to the first tank. The main diffe rence between CIL and CIP lies in the extent to

CIL: Since leaching and adsorption occur in the same tank, CIL requires fewer tanks, but each tank is larger and more complex in design. CIP: CIP requires separate leaching and adsorption tanks. Although there are more tanks, each tank is simpler in design and offers greater operational flexibility. 2.3 Gold Ore Characteristics
The CIL process requires the desorption of gold in the leaching tank, while the gold desorption in the CIP process is performed after solid-liquid separation. Overall, both CIP and CIL processes utilize activated carbon for gold adsorption, but there are some differences in the gold recovery steps and processes. ... The construction of a gold ...
