Jun 12, 2018· Use a metal rod or tongs to skim slag (thick clumps of nonaluminum materials) off the top of the liquefied aluminum. Then, with a pair of metal tongs, slowly remove the crucible from the foundry. To prevent oxidization, be sure to remove the molten aluminum from the foundry at least three minutes after the last piece of aluminum melted.

A small assay laboratory that analyses more than one ore type may well use a separate flux formulation for each sample if he has the whole rock to compare the sample with. A commercial laboratory on the other hand will be expected to process many thousand of different samples types, often present in the same work order.
