Enhancing diagnostic leaching methods Semantic

Diagnostic and selective leaching methods for estimating the leachable copper and identification of copper minerals respectively have been publically available since the 1930s. Use of leaching methods can provide advantages in sample preparation and analytical efficiency that compensate for any loss of mineral identification accuracy. However, routine procedures run the risk that results will ...
