The Process of Assaying Black Sands

The Process of Assaying Black Sands

Using a standard assay for iron oxide on magnetite/black sand does not work well. The magnetite is too chemically inert to dissolve, to any relevant extent, in the standard assay flux. As a result, it mostly remains undissolved and severely thickens up the assay glass so it does not pour and separate from the lead. This also results in no significant detectable amount of platinum group metals ...
