Precious metal filings are calcined to remove organic matter and impurities.<\/li>\n
A magnet is then run through the material to remove iron filings and sawblades.<\/li>\n
Flux is added to melt the filings into a button or bar.<\/li>\n
The button is then drilled, assayed and sent to the laboratory for recovery.<\/li>\n<\/ul>\n
