Estimation Of Gold Inventory In Large Carbon In Leach

May 01, 2011 Carbon is moved counter current of the slurry in the six CIL tanks on a 12 h basis. The striping circuit pressure Zadra consists of an acid leaching column, followed by an elution column operated in closed circuit with two electro winning cells. The stripped carbon is regenerated in a rotary kiln prior to being returned to the CIL circuit.

Aug 01, 2017 All the queried values are similar in these two cases. However, the process flowsheets are slightly different. The refractory sulfide ore Au 2.0 gt of the case T3 is pretreated by nonacidic pressure oxidation before leaching by carbon-in-leach. The oxidised ore of the case T3 is treated by carbon-in-leach followed by pressure zinc precipitation.
