Mixed Acid Digest & ICP
Bureau Veritas offers a wide variety of multi-element technique for your exploration, research definition, mine-site and metallurgical requirements.
Care and attention begin prior to any sample collection. Rock and core samples are dried then prepared by particle size reduction to produce a homogeneous sub-sample which is representative of the original sample.
Mixed Acid Digests offers a strong dissolution of most minerals with a choice of either ICP-ES or ICP-MS analysis. Acid attacks using nitric, perchloric and hydrofluoric acids breakdown many minerals, including silicates.
The highly cost effective technique provides near-total determinations for most elements, with low to very low detection limits. Low levels of rare earths may also be quantitatively recovered. More resistant metals such as Chrome Titanium, Magnesium, Zirconium and Tungsten are only partially attacked.
