Mineral Sample Preparation is a vital stage in the process of minerals analytical testing. The purpose of sample preparation is generally the production of a homogeneous sub-sample, representative of the material submitted to the laboratory. Correct preparation is critical to obtaining meaningful analytical results.
Ore-Assays Actlabs
Assays provide quantitative determinations of elements in non-processed geological materials. Assays are usually required when samples are known or suspected to contain higher levels of metals. Accuracy is typically in the 1-3% range as long as the analyte is greater than 100 times the detection limit of the method.
