Determination of Gold in Sulfurized Minerals by Spectrophotometry with Thiourea Sample Decomposition
-
ABSTRACT
In the medium of H 2C 2O 4 H 2SO 4 gold in sulfurized minerals can be decomposed by 50 g/L of thiourea solution with 99.8% of leaching out efficiency for gold. Gold then can be concentrated by chromatography with CL P 204 resin and determined
