Gold CIL & CIP Gold Leaching Process Explained CCD

Mar 17, 2017 . 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 carbon in pulp process.

Continuous Vat Leaching (CVL) & Glycine Leaching Technology .

GlyMine is the application of Glycine as a Lixivant in applications where leaching of valuable metals can be carried out by circulating the lixivant through bore holes into a permeable or semi permeable rockmass (in situ) or directly on broken ore (in place) with minimal handling and size reduction. Glycine is attractive over.

In situ leaching BioMineWiki

May 14, 2008 . In situ leaching is one of several leaching methods. In situ or in place leaching means that the metal values are leached directly from the ore without excavating the ore prior to leaching. Leaching reagents that dissolve the desired metals are pumped into the deposit through injection wells. The leachate is.

The gold bearing liquid is then separated from the leached solids in thickener tanks or vacuum filters, and the tailings are washed to remove gold and cyanide prior to disposal. The separation and washing take place in a series of units by a process referred to as counter current decantation (CCD). Gold is then recovered.
