Gold and PGMs

Sample Preparation is one of the most important steps in the analytical process. The goal is to achieve an homogenous sample or a sub-sample that is representative of the submitted material. If this is not achieved, then the analytical result can be biased or even meaningless! Therefore Set Point laboratories uses hi-tech crushing and milling equipment, with the sample preparation procedures accredited as separate entities on their own – apart from the analytical procedures.
Siza Coal Minerals Services offers various techniques depending on the testing requirements. Classic Fire Assay – Lead collection is used to accurately determine gold, platinum and palladium (and rhodium if required); and nickel sulphide collection determines all PGE elements (6E).
Depending on the testing requirements, either XRF or ICP-OES / ICP-MS can be employed to offer a full range of testing services.
