HP3 Global has a network of laboratories, offering you an unparalleled level of analytical expertise around the East Africa. For gold and silver bullion analysis and assay there are many different methods available, for example silver bullion can be analyzed by cupellation, by chemical titration, or by a combination of chemical titration and instrumental techniques.
HP3 Global has a network of laboratories and offers you an unparalleled level of analytical expertise. There are many different analytical methods available in the industry to develop geochemical targets. There are several digestion techniques that can be used depending on the end use of the data – from very weak extraction to complete dissolution. Aqua regia extractions are good for many elements including gold and base metals.
Fire assay is the industry standard process for obtaining gold and platinum group element (PGE) concentrations from high-grade ores.
Lead collection gold fire assay is considered the most definitive technique for gold analysis. Platinum and palladium can also be determined by this method, but the full PGE six-element suite is best determined by nickel sulfide collection fire assay. HP3 Global experts are always available to help you select the analytical technique that is fit for your purposes.
The erratic results that arise from visible, nuggety gold are a problem around the world.
HP3 Global can help you address this issue, also known as nugget effect, with precious metal analysis and assays in any of the laboratories in our network.
Our unparalleled level of analytical expertise means we know how to sample and treat such materials. The screen metallics method, also known as pulp metallics, is used to obtain better reproducibility when metallic gold is present in the ore.
