1.0 INTRODUCTION - Sustainable Leaching Technology

The mining and material handling process has been unmodified for the 10,000t/d Continuous Vat Leach case, and modified only as a result of the reduction in processing rate for the 5,000t/d CVL case. The crushing circuit has been modified as a result of the Continuous Vat Leaching process feed size requirement of -6mm.

Vat Leaching of Finely Crushed Gold Ore

Vat leaching is carried out in vats ranging in capacity from 30 to 1200 tons. Sand for leaching is separated from slime in cones, V boxes, classifiers, and in collecting vats filled by distributors—the overflow in each case being slime or finer portion of the ore. As a rule, leaching is a simple process, involving a vat of well-mixed neutralized sand, ample contact with strong and weak ...

Gold CIL CIP Gold Leaching Process Explained CCD

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.
