Diagnostic leach test
WebDiagnostic leaching is a cost-effective and simple alternative to these mineralogical characterisation tools and uses low-cost, small-scale tests to characterise a large number of samples of low mass. Traditionally, these leach tests provide information on valuable element recovery, grade and may WebThe comparator test results should have a diagnostic accuracy meeting the medical laboratory specifications. The measurement directly depends on these results. For instance, if the comparator has a worse performance than the new test, the validation could be misinterpreted. All discrepant results should be evaluated using a confirmatory scheme.
