is formed, as shown in Reaction 6. The resin has no affinity for the positively chargedgoldthiourea complex and the gold reports to the eluate stream. P – NR 3 +Au(CN) 2+ 2TU + 2 H 2SO 4 → P – NR 3 +HSO 4+ Au(TU) 2 +HSO 4+ 2HCN Reaction 6 A disadvantage of the use of SBA resins for gold cyanide recovery is the fact that thiourea is a
The adsorption thermodynamics, kinetics, and isotherm parameters of cefpirome sulfate in aqueous solution on macroporous resin (XAD16) were studied. Using static equilibrium tests, the fitting of resin adsorption data were calculated by the isothermal adsorption model. The fitting results show that Freundlich equation can adequately fit the adsorption isotherm.
Adsorption tests were done with two adsorbents, DowexMinix goldselective resin and CQ650 coconutbased activated carbon. Clarified solution from the millingincyanide operation was used as pregnant liquor for these tests. The DowexMinix resin was converted to the SO42form, prior to use. Resin volumes were measured as tapped
