The CIL (Carbon in Leach) circuit is an intermediate stage in the production of gold. The process involves dissolving the solid gold particles into solution using a process know as cyanidation. The dissolved gold in solution is adsorbed onto activated carbon. When the carbon is loaded
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. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.

Gold in these circuits occurs as a layer over a base metal substrate such as nickel or copper. Separate the goldplated metal parts in the circuit boards using a magnet. Some goldplated parts may be inside ceramic components. Put on the goggles and gloves. Place all of the recovered circuit parts in one of the glass containers.
Gold has a special place among metals. It is the oldest metal exploited by man, it plays an important role in world economics, it is highly prized, it was the ultimate goal of alchemists, and it is stored in the vaults of banks. Gold has been used in gilding, to make funeral masks, and for many other uses.

CIL 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.

Introduction to Printed Circuit Boards The Printed Circuit Board ... typically gold (Au), silver (Ag) and platinum (Pt). ... industry is to heat the sludge to 600750°C to remove the excess amount of water and to convert the copper hydroxide to copper oxide.
The carbon is then cooled, screened to remove fines and is ready for reuse. Fines are not desirable in carbon circuits, since they will escape through the carbon screens and end up in the leach, capturing gold that will not be recovered. For this reason, high quality and hard carbon is generally utilized for these applications.

A CIL circuit was later added to enhance gold production. Three decades had passed before DRDGOLD acquired the Brakpan plant in 2007 with the aim of reestablishing the Ergo project. During this period, many variables had changed, including the closing of the flotation circuits at all plants. The Brakpan plant was therefore reestablished using ...
