Solidphase partitioning of mercury in artisanal gold mine

The solidphase partitioning of mercury could provide necessary data in the identifiion of remediation techniques in contaminated artisanal gold mine tailings. This study was conducted to determine the total mercury content of mine wastes and identify its solidphase partitioning through selective sequential extraction coupled with cold vapour atomic absorption spectroscopy.
