tsx-listed wa gold producer, novo resources has moved to speed up the process for receiving its gold assay results. the company has now secured a deal with intertek testing services that will see the latter provide on-site laboratory and sample preparation services and photonassay services.,assaying | chemical process | britannica,assaying, in chemical analysis, process of determining proportions of metal, particularly precious metal, in ores and metallurgical products. the most important technique, still used today, grew largely out of the experiments of the ancient alchemists and goldsmiths in seeking to find or create precious metals by subjecting base metals and minerals to heat.
an assay is an investigative (analytic) procedure in laboratory medicine, mining, pharmacology, environmental biology and molecular biology for qualitatively assessing or quantitatively measuring the presence, amount, or functional activity of a target entity (the analyte). the analyte can be a drug, biochemical substance, chemical element or compound, or cell in an organism or organic sample.,ore-assays - actlabs,the principle advantage of this technique is it provides very rapid and accurate assays of uranium for high volumes of samples at a very low cost. the upper limit of this technique is 1% u. results can be reported as u or u3o8. from 1 to 10% fusion xrf will provide the best quality assay results and above 10% titration is recommended for accuracy.
