摘要
The different acid systems of aqua regia, HF+HClO4 and HCl were chosen for dissolving tests for Ni-bearing laterite samples. Results indicated that using aqua regia to dissolve samples with the support of HF acid and adding HClO4 acid to remove HF, is an ideal method for Ni-bearing laterite. The sample solution was dissolved by HCl before loading to determine Ni, Cr, Mg, Al and Co by inductively coupled plasma emission spectrometry (ICP-MS). The experimental results show that the recovery factors of Ni, Mg, Al and Co were 96.83%～105.23% with a relative standard deviation (RSD) of less than 3.3%, except Cr. The element determination results (except Cr) were in good agreement with certified values of standard materials.
