Adsorption tests were done with two adsorbents, Dowex-Minix gold-selective resin and CQ650 coconut-based activated carbon. Clarified solution from the milling-in-cyanide operation was used as pregnant liquor for these tests. The Dowex-Minix resin was converted to the SO42-form, prior to use. Resin volumes were measured as tapped
2.5.1. Adsorption Resins Screening. All macroporous resins were screened through static adsorption test. Pretreated resin (equivalent to 1 g dry resin) was put into a 50 mL Erlenmeyer flask with stopper and 10 mL aqueous solution of S. cuneata extracts in Section 2.3 was added. The flasks were shaken (180 rpm) for 8 h at 25°C.
