Kinetics of Yttrium Dissolution from Alkaline Fusion on

26/05/2020· Alkaline fusion was carried out for 3 h at 450 °C, with a ratio of sodium hydroxide to zircon tailings sand of ~ 1:1. The alkaline fusion product was leached with water, followed by hydrochloric acid treatment to leach the yttrium. Yttrium recovery reached 87% under optimum conditions (60 °C, 1 M HCl, and solid to liquid ratio = 1/10 for 7.5 min).

238U/235U Systematics in Terrestrial Uranium Bearing Minerals

The observed variability in 238 U/ 235 U zircon may limit precision for 1 Ga zircon samples with no independent 238 U/ 235 U constraint. For 207 Pb 235 U and 206 Pb 238 U dates ( Fig. 2, B and C ), the mineral 238 U/ 235 U is used in tracer subtraction and fractionation correction calculations for tracers enriched in 235 U that are commonly used in high precision U Pb
