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

Equilibrium data for the adsorption of gold tetrachloride from aqueous solutions of four different concentrations of hydrochloric acid (,,, and mol·dm −3 HCl) by macroporous crosslinked polyacrylate (MET) resins which have the same functional groups and different structural characteristics have been obtained at a temperature of 25 ± °C.
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.
The extract was concentrated under reduced pressure, and then dissolved in 30% ethanol to give 1 g/ml (crude medicine/volume) sample liquor, and then this liquor was passed through AB8 macroporous resin column with 1 time the volume which was comparable to the weight of macroporous resin.
FIELD: metallurgy. SUBSTANCE: proposed method comprises preparing leaching solution bearing gold, and gold sorption by macroporous resin containing alkyl amine functional groups in amount of mmol/g and 312% of crosslinks with water retaining capacity making, at least, 30%, and specific surface area varying from 400 to 1200 m 2 /g. After sorption, gold is eluted.
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
