Abstract

"In presenting the within thesis, it is not claimed by the authors that the experiments have been, by any means, exhaustive of the subject. Neither is any claim made to original research work other than a series of simple experiments with a view to determining, if possible, some of the more important effects of Arsenic upon a fire assay for gold and silver as met with in the ordinary assay laboratory. To make a work complete and exhaustive on such a subject will require much more time and more complete apparatus than was available in the experiments covered by this thesis. The experiments have been intended to cover both fusion by crucible, and cupellation, as well as the wet assay of slags, cupels and lead buttons. Briefly stated, the problem presented in this paper is to locate the sources of loss in a fire assay for gold and silver, due to the impurity, Arsenic, and its compounds, and to ascertain, if possible, the remedy for those losses. The solution of the problem is proposed by means of the scheme outlined in the following flow sheet:-"--Page 1.
