pyrometallurgy zadra elution circuit

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. You should be achieving optimum elution with about 30 BV of eluant through the column (15h at 2BV/h).

yes. You get Zadra systems for 1 tonne. The adsorbed carbon needs to be eluted through the elution column with 4% caustic and 2% cyanide solution at around 130 deg C. The gold bearing strip solution is called as pregnant solution which then has to go through the EW cells and gold gets deposited in Cathode (Stainless steel wool).

technical buliton zadra electrowinning system

Oct 01, 2019· The key role in elution is played by temperature, in a Zadra system not much happens below 90C. Pressure Zadra is run around 110C but can vary depending on the subtleties of the system. Pressure Zadra is much faster than unpressurised Zadra, depending on the operating conditions around 12 hours versus 48 hours.

(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.
