Mineral-PET is a technology for the sorting of diamond bearing rock (kimberlite ore) based on a mineral analogue of the well-known medical Positron Emission Tomography (PET) imaging technique. The naturally occurring carbon in kimberlite needs to be activated via photonuclear transmutation before it can be imaged. For the R&D phase of the project, a technology demonstrator has been built. This is a planar PET array built around a conveyor belt using kimberlite phantoms. The phantoms consist of blocks of cement with the radioactive material (Na-22) uniformly distributed throughout it to simulate the homogenous background radiation from various non-diamond PET emitters. Diamonds are modeled in the phantom by the inclusion of a localized “hot-spot” of Na-22. This system has been used to benchmark computational simulations and to explore the physics issues for the specification of a pilot scale plant at a mine. The review will provide new results and updates on the performance and outlook for Mineral-PET.
