The ZADRA system is another elution process where gold that is adsorbed on to activated carbon is desorbed from the carbon by a reversal of the adsorption kinetics. The ZADRA elution circuit at...
26-02-2020· The Elu-X is an open Zadra elution system that strips the gold off the loaded carbon that is produced in the TriTank plants and this completes the process. To keep these small scale systems as safe as possible, the Elu-X is non pressurized and thus operates just below boiling point. The result is that an elution cycle lasts typically two days ...
07-09-2018· The eluate solution used in the Zadra elution process is typically 0.2 - 0.5% NaCN and 1 - 2% NaOH. All operating variables that apply to the AARL elution system apply to the Zadra system. The caustic cyanide solution is pumped to the elution column at 2 to 3 bed volumes (BV)/hour, and is pre heated by the solution exiting the column.

If your gold balance overall dictates that you do a 4 or 6 or 12 ton elution per day, then your elution should be done in the same day to maintain the inventory balance- in a Zadra system 18-20 hrs recycle is not uncommon even honouring all metallurgical parameters- it also depends on the cell activity, frame quantity, power draw, water quality etc. monitor the column outlet tenour to the electrowinning cell and …
Once or twice per week the carbon was treated in a 15tonne pressure Zadra strip process. Gold was recovered from the pregnant solution on stainless steel wool cathodes in the refinery. From 1996 onward, much of the tailings were returned to the mine as pastefill backfill.

John Zadra set to work and in 15 months developed a carbon adsorption/desorption process using hot sodium hydroxide-cyanide solution to strip gold and silver values from carbon and an electrolytic mass transfer cell, the Zadra cell, to plate precious metals from the solution onto steel wool.
zadra mining process - abbaziapertutti. Atmospheric pressure Zadra stripping was the first commercially successful process developed for stripping gold from carbon. The process was developed by J. B. Zadra, and others, at the U.S. Bureau of Mines (USBM) in the early 1950's. Get Price
Croatia is not expected to be free of mines for quite some time. The most heavily mined areas were in . eastern Slavonia near Osijek and Vukovar, western Slavonia around Sisak and Karlovac; the hinterlands behind Zadar and Sibenik. De-mining is a slow and expensive process.
19-11-2019· 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 2-4 BV/h range.
The strip process is called a Zadra process now and it was named after a man named Zadra. I think he worked for the US Bureau of Mines and developed the strip. It's not brand new, but it's a relatively recent technique – probably about as old as me. Merrill-Crowe is quite a bit older.

This process has literally made many mines by taking low grade geological resources and transforming them to the proven ore category. Ore grades as low as 0.01 oz Au per ton have been economically processed by heap leaching. Heap leaching involves placing crushed or run of mine ore in a pile built
