Is caustic fusion, rather than an x-ray sorting process. At: http://www.src.sk.ca/html/labs_facil... Per: " Diamonds The following services are offered: Caustic Fusion and Chemical Processing Diamond Observation and Weighing Diamond Description and Photography Sample Handling To assure the integrity of the process, a chain of custody is established between the customer and the laboratory . Customer samples are processed in a controlled environment to ensure that confidentiality is maintained at all times. All samples are handled according to defined security protocols during processing stages. Method Summary An 8Kg sample is fused in a kiln containing caustic . The hot residue is then poured through sieves and the selected material is then chemically treated to reduce the residue to a manageable size. The residues are then observed and the diamonds recovered..." ----------------- While the picture on diamond page on the website makes it appear there may be multiple kilns, it is not readily certain that the kilns in the picture are used for caustic fusion. If they are the caustic fusion kilns, the fusion process may be much faster than the "8Kg..." reference might indicate, or they may be able to run multiple 8Kg samples through the kilns at the same time. By the looks of the crucible shown being lowered into the kiln, I would estimate perhaps as much as 1.5 to 2 cu ft capacity, perhaps more. Seems like a lot of volume capacity for an 8 Kg sample.... Speculating more, at a specific gravity starting at 3, possible number of kiln runs might be about 9 at a calculated capacity (for 1.5 cu ft size) of 127 Kg, per -- unless there is more caustic solution required than simply covering the sample with some outage space. Then the processed caustic mix has to be sieved and the sieve quantities have to be apparently hand-sorted for diamonds. I'm thinking that top sieve could be a doozy! Looks like it will take a while to process.... Above all, this processing represents a series of historical firsts for Canadian diamond exploration. ...First Canadian bulk sample of a kimberlite with green garnets (G12s). ...Likely the first Canadian processing for an outside company where DeBs did the DMS processing free with no strings attached.
