Desulferizing, or pot roasting of lead ores
"In this thesis for a starting point, we attempted a roast of straight galena with no diluent. As anticipated the results were nil. We next attempted the roast with a mixture of galena and silica, and obtained fair results. Our next experiment was to use limestone with the galena. Because of the large percentage of limestone present the results were not satisfactory. Next pyrites and limestone were used with the galena, and excellent results were obtained. We made another run, using pyrites and limestone, but increasing the per-centage of galena by 25%. This run was also very successful. From these few runs, the data we are able to glean from periodicals, and the rational chemical analysis that we made on the roasted product, we base our thesis"--Introduction, pages 1 -2.
