ASTM C967-08
(Specification)Standard Specification for Uranium Ore Concentrate
Standard Specification for Uranium Ore Concentrate
ABSTRACT
This specification covers uranium ore concentrate. Chemical composition shall have a minimum content requirement for uranium and a limited content for uranium isotope, insoluble uranium, extractable organic, and impurities. Uranium ore shall also conform to chemical analyses, particle size, flow ability, and foreign matter contents according to the specification. Standard packaging requirements for uranium ore shall also be met according to the specification.
SCOPE
1.1 This specification covers uranium ore concentrate containing a minimum of 65 mass % uranium.
1.2 This specification does not include requirements for health and safety. Observance of this specification does not relieve the user of the obligation to be aware of and conform to all applicable international, national, state, and local regulations pertaining to possessing, shipping, or using source nuclear material (see 2.2).
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

INTRODUCTION
This specification is intended to provide the nuclear industry with a general standard for uranium
ore concentrate. Material conforming to this specification will generally meet the requirements for
conversion to uranium hexafluoride. However, the converter may relax or supplement this specifica-
tion upon mutual agreement with the customer.
