Abstract
THE precipitation of phosphoric with titanic acid, by boiling an iron solution which had been reduced to the ferrous condition by sulphuretted hydrogen or sulphurous acid, was first noticed by E. H. Bogardus in 1874.* Since that time, as far as we are aware, not much has been published on the relation- of these two acids to each other, and to silicic acid, in the ordinary course of analysis of iron ores. The following investigation may perhaps aid in clearing up some of the obscure points in the analysis of titaniferous ores. THE DETERMINATION OP PHOSPHORUS. From two to five grams of the finely powdered ore are weighed into a beaker and treated with about 50 c.c. of hydrochloric acid (sp. gr. 1.12), evaporated to dryness, and heated in an air-bath for * American Journal of Science, III, 8, p. 334.
