heated at elevated temperatures in the presence of steam to create activated carbon In gold recovery applications, activated carbon manufactured by Thermal activation is used This process will be discussed in more detail There are a number of steps in the production of ,
The Anglo American Research Laboratories AARL carbon stripping system used in this EXAMPLE has two definite advantages when compared with its most common counterpart, the Zadra system It is much less expensive to operate and it produces a cleaner stripped carbon It is however very reliant upon the availability of an abundant supply of good quality water and its water usage is far greater .
Elution Circuit Components Elution Column The elution column is a 10m high by 12m diameter mild steel rubber lined pressure vessel (rated to 350kPa) Having a high ‘length to diameter’ ratio enables solution to flow evenly through the bed of carbon without short-circuiting or ‘tunnelling’
In the case of Zadra elution, where the electrowinning cell is in series with the elution column, the column and cell must be designed to elute and recover the gold by recirculation of the eluant until the gold content of the eluted carbon is low enough (

Zadra elution circuit - Pyrometallurgy: Roasting, Smelting , Not process water E/W single pass efficiency is critical for Zadra because gold not recovered is then re-circulated back to the elution column, slowing down the elution rate Eluant flowrate is not too critical in the 4 BV/h range
The plant has two pressure Zadra elution circuits rated at 20 tons of carbon per , A gravity gold recovery circuit was retrofitted in 2003 to the Beatrix plant and each mill , The plant receives underground ROM (run of mine) ore from Beatrix 4# , covering both sets of TSF operations specifies freeboard, and , »More detailed

The ZADRA elution circuit at Gold Fields Ghana Limited was designed as a pressure system with an operational pressure set point of 350 kPa It consists of circulating 3% sodium hydroxide water .
The oxide circuit was based on the use of the Kori Kollo plant and the difference with mixed , Gold is recovered through a conventional pressure Zadra , purchase did not include the elution gold room , carbon regeneration or reagent sections Zadra elution circuit - Pyrometallurgy: Roasting, Smelting .
(2) A caustic/cyanide presoak may be used in a Zadra system (3) A hot water wash is sometimes used at the end of a pressurized Zadra strip to gain some of the advantage of the water elution used in AARL stripping (4) In situations where large amounts of copper load onto carbon with the gold and silver, a two stage strip may be beneficial
Modular Elution Circuits with Gold Room Como Engineers >Modular Plants , Como Engineers has refined the Zadra elution process and optimised it to run with the highest efficiency through proprietary system designs which optimise system flows, elution temperatures, electrowinning cell and rectifier designs and reagent combinations .

Zadra elution circuit (4 replies and 1 comment) Sachin Prakash 4 years ago Sachin Prakash 4 years ago How to avoid abnormal long elution period from a zadra elution circuit, is this cyanide depletion, eluant composition, flow of eluant to electrowinning cells or temperature? Bob Mathias
131 Elution Circuit Figure 1 shows a flow sheet of the elution circuit The elution column operates with a 2-25% NaOH solution with a temperature range of 120oC-135oC The gold is stripped from the carbon into the solution An elution will start when there is ,
