Avoiding Precipitation During Mining Sample Prep

Send a text

This week on Bench Boost the team from Inorganic Ventures discusses avoiding precipitation during sample preparation. They review mining sample challenges including high concentrations of Ca, Fe, Al, & silicates, sulfate-rich matrices forming insoluble sulfates, and rare earth elements requiring a more acidic matrix. Thomas explains how hydrolysis leads to insoluble metal hydroxides and reviews prevention strategies. Liv outlines how to use Ksp and how temperature effects compound solubility. Lastly, Autumn covers alternative ligands, such as EDTA, for higher pH stability.
