RADIOACTIVE DECONTAMINATION OF CONTAMINATED MINERAL/WASTE

Patent Number : MY 138054-A / MY 135419-A

 

Naturally-occurring radioactive radioactive elements such thorium, uranium and radium are found in many minerals and wastes produced by the downstream processing of these minerals. Among the Malaysian minerals found to contain these natural radioactive elements are by-product from the tin mining activity such as monazite, xenotime, zircon, ilmenite and rutile. It is also presence in waste produced from the downstream industries such as that found in the tin slag waste. The project aims at developing a process of selectively removing these radioactive elements from the mineral/waste and thus produces mineral/waste that can be reused by the industry. Among the novelty of this project is the used of industrial carbide waste as possible decontamination agent for the removal of the natural radioactive elements.
