Portable XRF for Indicative Analysis

Portable XRF is useful for screening large numbers of intermediate to ore grade elements quickly and cost effectively while awaiting standard lab analyses. It can also be used to determine Si and acid-resistive Ti and Zr as a complement to multi-element methods and a proxy for rock characterisation. For a successful pXRF scan it is important that calibration is matched to specific sample suites on an individual project basis to minimise inaccurate results. ALS offers custom calibration for pXRF on project- specific sample suites, with our rigorous quality standards and XRF expertise ensuring accurate, reliable results. The pXRF instrument can be located in the prep lab nearest your project, or on-site if the project is remote. Contact your local client services team for more information.

USD 2021 | SCHEDULE OF FEES AND SERVICES | GEOCHEMISTRY | 11 Precious Metals Analysis

The unique chemical properties of gold, silver, and the platinum group elements pose challenges in geochemical analysis. They often occur heterogeneously in geological materials, at scales ranging from micron-sized inclusions in minerals to large nuggets. As a result, large analytical charge weights are required to accurately represent content in the overall sample. Solvent digestions can also lose gold to adsorption on the original sample when certain forms of carbon and sulphide minerals are present, in a process called preg robbing. ALS has decades of expertise in reliable and reproducible precious metals analysis by fire assay, cyanide leach and aqua regia digestion at parts per billion to percent levels.

All of the ICP-MS methods listed in the following section involves some aspect of our innovative methodology for super trace analysis. Detection limits have been pushed orders of magnitude below average crustal abundance for the majority of elements, enabling excellent precision at geochemical background levels and clearly defined geochemical anomalies. Digestion methods appropriate for any sample medium are available - soils, sediments, regolith, vegetation, water, rocks, and drill core. ALS remains committed to solving long-standing analytical challenges in exploration geochemistry by making use of new instrumentation and fresh ideas from our team of expert analytical and geochemists.

No single method covers all types of geological materials for all geochemically-relevant elements at all concentrations. Sample type, commodity of interest, geochemical pathfinders and expected concentration of target elements should all be considered when selecting appropriate methods for your project.

Broadly, aqua regia readily dissolves many sulphide, oxide and carbonate minerals, as well as retaining mercury, a particularly volatile element. Four acid digestions quantitatively dissolve nearly all minerals, but it may sometimes be necessary to use even stronger techniques such as fusions in order to fully digest barite, rare earth oxides, and tin, tungsten, niobium and tantalum minerals.

The choice between various instrument finishes should be informed by the expected concentrations of the elements of interest in the sample.

The investigation of geological and ore forming processes is enhanced by targeted lithogeochemical analyses that are often carried out on a sub-set of samples during a thorough geochemical program. They are used to fully characterise rock type, along with changes due to , alteration and mineralisation. As there is no single analytical method that can fully define the full range of elements that are required for effective lithogeochemical investigations, ALS offers packaged combinations of analytical methods most appropriate for every element and designed to provide comprehensive information for, essentially, complete rock characterisation.

A wide variety of sulphur and carbon minerals and compounds are often found associated with ore deposits. These minerals can impact ore processing and how waste can be stored during mining. Identifying what form these elements are present in has important implications for ore and waste characterisation. These methods are also powerful tools when combined with large geochemical data sets for geometallurgy investigations.

Please submit at least four times the nominal sample weight for efficient service.

Procedures for the evaluation of ores and high grade materials are optimised for accuracy, precision and recovery of the target element. No single digestion or analytical method is suitable for all cases, and ALS provides a wide variety of procedures so the most appropriate method can be selected. Choices include acid digestions with ICP-AES finish; fusion and XRF determination for resistive elements and bulk commodities; specialised solvent digestions for uncommon ores; and classical volumetric methods for very high grade base metals.
