Field Application of Portable XRF with Glass Bead Certified Reference Material(CRM) in Nickel Laterite Deposit

Following QA/QC procedures, portable XRF (p-XRF) field tests were performed on borehole samples from nickel laterite deposits and the results compared with lab-XRF results. To verify reliability accuracy of obtained by p-XRF in field, certified reference materials prepared as glass beads analyzed together samples. The showed that overall contents each element generally lower wet than pulp samples, trend content depth was related to degree weathering laterite. For interest, Ni, correction using Ni-Fe correlation calculated values found be similar derived coefficient applied another sample confirm its applicability other boreholes. corrected a decrease deviations data, confirming validity method.
