Table 2. Typical Contaminant Solution Concentrations Prior to (A) Silica Precipitation and (B) Uranium-phosphate Precipitation^a.

contaminant	U	Si	Sb	Mo	Fe	Al	Mg
(A) silica precipitation-stage 2 (mg L^–1)	200	20 000	1800	300	30	30	20
(B) uranium precipitation-stage 3 (mg L^–1)	28*	107	38	44	6	4	10

Concentrations determined by ICP-OES (* represents that uranium concentration is lower due to dilution).
