Of Gold By Chlorination

chlorination method of gold extraction.However this was not the primary object of these tests.That was to compare the methods.In allcases-where the amoul'lts of reagel1ts were proportional, the bleaching powder gave the best results.The manganese dioxide gave very irregular results,vlhich irregularity i cannot account for.
