1.1 These test methods cover procedures for the chemical and atomic absorption analysis of uranium-ore concentrates to determine compliance with the requirements prescribed in Specification C 967.

1.2 The analytical procedures appear in the following order:

Sections
Uranium by Ferrous Sulfate Reduction-Potassium Dichromate Titrimetry 9
Nitric Acid-Insoluble Uranium 10 to 18
Extractable Organic Material 19 to 26
Arsenic by Diethyldithiocarbamate (Photometric Method) 27 to 36
Carbonate by CO2 Gravimetry 37 to 43
Fluoride by Ion-Selective Electrode 44 to 51
Halides by Volhard Titration 52 to 59
Moisture by Loss of Weight at 110°C 60 to 66
Phosphorus by Spectrophotometry 67 to 75
Silicon by Gravimetry 76 to 82
Thorium by the Thorin (Photometric) Method 83 to 91
Calcium, Iron, Magnesium, Molybdenum, Titanium, and Vana-dium by Atomic Absorption Spectrophotometry 92 to 101
Potassium and Sodium by Atomic Absorption Spectrophotometry 102 to 111
Boron by Spectrophotometry 112 to 121

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.
