Differences Between CIL and CIP Gold Extraction

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

Modeling and optimization of Carbon in leach (CIL) circuit …

The aim of modelling and simulation of CIP/CIL tanks is limited to either refining the models used for simulations or optimizing the process using operating parameters. For improving the models to simulate CILs, van Deventer and Ross (1991) reviewed the developments in CIP systems and concluded that preg-robbing is an …

2nd CIP Who needs it a combination circuit of gravity, …

with the Merrill Crowe Process, CIP or CIL the use and further development of gravity concentration devices for the recovery of gold in modern gold plants went into decline. Limitations of the CIP/CIL process recently saw the re-emergence of gravity concentrators either in the grinding circuit or in treating the CIP/CIL tailings in many operations.

What is an interstage screen?

The main difference between CIL and CIP lies in the extent to which gold is leached prior to carbon adsorption. In CIL operations, carbon is added to the leaching tanks, therefore the leaching reaction and adsorption occur simultaneously. During the CIP process, most of the leachable gold has been leached prior to the first adsorption stage.

Understanding the CIP Cleaning System: An Essential Guide …

Employee Safety: Safety for staff members should be given priority during the operation of CIP systems. This includes putting in place right safety measures while handling cleaning chemicals as well as training workers on how to work safely with and maintain CIP equipment. In addition, employees must use personal protective …

Control Design for CIP Systems

Successful CIP operations require careful control of these cleaning solutions, using time, temperature, chemical concentration, and mechanical action to achieve satisfactory performance on a repeatable basis. A functioning cleanable process uses a CIP unit, generally skidded equipment, designed to accomplish the make-up and delivery of …
