Weighing and sampling of uranium concentrates, U3O8, are critical steps. Honeywell-MTW weighing and sampling procedures, which conform to ASTM standards, help determine the purity of uranium concentrates and ensure compatibility with the Honeywell conversion process.
Honeywell conversion process
- Uranium ore concentrates are received at the Metropolis Works Sampling Facility in U.S. Department of Transportation approved containers.
- Individual drums are accurately weighed.
- Drums are hydraulically lifted two at a time into the sampling augers.
- The auger system obtains a representative sample from each lot by removing a very small sample of the uranium ore concentrates in each drum from a random section of the drum’s contents.
- This material is then split, blended, ground and dried in order to prepare six 150 gram samples for analytical purposes (2 for Honeywell, 2 for the supplier and 2 for possible umpire use).
- The analytical results must be agreed upon by Honeywell and the supplier prior to conversion.
