- Abstract
Critical minerals (CMs) such as nickel (Ni), cobalt (Co) Co, chromium (Cr), manganese (Mn), and zinc (Zn) are materials essential to the economy, but the supply is vulnerable to disruption. Ni laterite deposits are considered potential sources of these CMs. In this study, the Ni, Co, Cr, Mn, and Zn contents of 15 Ni laterite samples from Zambales and Surigao were determined using handheld laser-induced breakdown spectroscopy (hLIBS) and handheld X-ray fluorescence (hXRF) analyzers. The samples were also analyzed using inductively coupled plasma mass spectrometry (ICP-MS) to compare the handheld analyzers with the established laboratory technique. The two-sided t-tests show no significant differences between the average Ni, Cr, Mn, and Zn results of hLIBS and hXRF with respect to ICP-MS. The average hXRF result of Co significantly differs from ICP-MS, whereas hLIBS has no significant difference from ICPMS. Therefore, hLIBS and hXRF can be used to determine the Ni, Cr, Mn, and Zn contents in laterites, whereas hLIBS can be utilized to determine the Co values of laterites. Both hLIBS and hXRF analyzers can be for CM exploration of Ni laterite deposits.
